3 About ALMAThe Atacama Large Millimeter/submillimeter Array (ALMA) enables transformational research into the physics
of the cold universe, where the sky is dark in the visible part of the spectrum but shines brightly at(sub)millimeter wavelengths. ALMA is a global collaboration involving partners in North America, Europe, andEast Asia, in cooperation with the Republic of Chile. The telescope has 66 high-precision antennas located on
the Chajnantor plateau of the Chilean Andes, 5000 m above sea level. In Full Operations, ALMA will image thesky at resolutions as fine as 0.005” with unprecedented sensitivity, and will operate at frequencies between
35 GHz and 950 GHz. The capabilities of ALMA are outlined in the Proposer’s Guide and details on thetelescope are given in the Technical Handbook. New users can learn about ALMA and get an introduction toradio interferometry in the ALMA Primer. These documents are available at the ALMA Science Portal website,
found at http://almascience.nrao.edu.

4 Organization and Role of the ARCs and the NAASC
Being an international facility, ALMA serves a worldwide community of astronomers, scientists, and otherprofessionals. To interact with the geographically distributed user community, the three partners haveestablished ALMA Regional Centers, or ARCs. They are the North American ARC (NA ARC), based in
Charlottesville, VA; the East Asian ARC (EA ARC), based in Mitaka, Japan; and the European ARC (EU ARC),
based in Garching, Germany. The ARCs are staffed by scientists with expertise in radio astronomy,
millimeter/submillimeter astronomy, and interferometry, and their purpose is to work with the scientificcommunity to maximize the productivity of the ALMA telescope. The NA ARC is part of the NAASC,
concentrating on internationally sanctioned core ALMA functions.
Each astronomer who uses ALMA is assigned an ARC for user support at the time they register with the ALMA
Science Portal. Astronomers in North America, East Asia, or Europe are assigned to the ARC associated with
their region. Astronomers from Taiwan can select either the NA ARC or the EA ARC. Astronomers elsewherein the world can select any one of the three ARCs.

Helpdesk staff will make every effort to respond to tickets promptly. During normal operations, users can
expect a response within two business days. During the last week before the Call for Proposals, a single
department called “Proposal Submission Emergency” is set up across all ARCs that will answer urgent tickets
concerning proposal submission. Triage for this department will start 72 hours before the deadline with 24hour coverage by Europe (EU), North America (NA), and East Asia (EA).

6 Getting Help from the NAASC at Each Step of Your Project
The NAASC provides user support through all stages of an ALMA project, from learning the observatory’s
capabilities to the publication of results.
76.1 Learning about ALMA: Documentation, Workshops, and Community Days
Preparing for an ALMA project begins with learning the observatory’s capabilities and the tools needed todesign observations, prepare proposals, and submit proposals. The NAASC provides user documentation,
including Observing with ALMA: A Primer, at the ALMA Science Portal.
The NAASC helps to organize NRAO Community Days and other regional workshops in the USA and Canada topromote ALMA to the astronomical community and describe the tools needed to write proposals. These
workshops focus on preparation of proposals and observations, and feature talks on the observatory’s
capabilities, mm/submm interferometry observing techniques, and the tools required to design effective
ALMA projects. Attendees learn to use the ALMA Observing Tool (OT), the software used to prepare andsubmit observing proposals. The workshops may include a hands-on session to introduce attendees toimaging ALMA data with CASA. At the request of the hosts, the workshops may also include talks andinformation on CASA tasks for simulating ALMA observations. Future workshops are arranged in response to
the level of interest from the user community. NRAO Community Days and ALMA workshops can be organizedand hosted by university groups or research institutes, or can be tied to other scientific meetings orworkshops.
The NAASC also supports NRAO special sessions, splinter sessions and training events at AAS meetings andother meetings of the astronomical community throughout the year. These events promote all NRAO
observing facilities, and include a focus on the tools needed to prepare effective proposals. NAASC staff
describe ALMA capabilities, NAASC support services, ALMA user tools, and CASA data reduction and analysis
techniques.
Finally, the NAASC hosts periodic workshops that focus specifically on data calibration and imaging. These
workshops are aimed at helping users process their own ALMA data or archival data.
To request a community day event at your institution and/or see a list of workshops, Community Days, andtraining events, visit the workshops page directly at: https://science.nrao.edu/facilities/alma/community1
Registration is required for workshops and Community Days, and is available on the website.

6.2 Proposal Preparation
A Call for Proposals is issued prior to each scheduling period, or "Cycle". The Call and supporting documents
are made available on the Science Portal (see Section 5.1). These documents describe the capabilities of theobservatory for the upcoming Cycle and the policies and procedures for submitting proposals.
ALMA proposals are prepared using the ALMA Observing Tool, an application that can be downloaded fromthe Science Portal. Proposals must include a scientific and technical justification, a list of targets andfrequencies to be observed, and details such as the sensitivity and angular resolution required to meet thescience goals. The Observing Tool includes a sensitivity and exposure time calculator. Users must be
registered with the Science Portal to be able to submit proposals using the Observing Tool.
NAASC staff are available to help users learn how to use the Observing Tool and prepare proposals. We
emphasize here that the Observing Tool is not only used to assemble and submit the scientific and technicaljustifications, but also to design and specify fully the observations, so users are encouraged to become familiar
with the Observing Tool well in advance of the proposal deadline. The Helpdesk (see Section 5.3 of this guide)
is the primary resource for those seeking assistance. It may be possible to arrange face-to-face assistance at
the NAASC for particularly challenging proposals (Section 6.5).

The CASA task simalma, and the lower-level tasks simobserve and simanalyze, allow users to simulate an ALMA
observation of a target based on a model with a given source position, structure and brightness. These tasks
also help potential ALMA users visualize how different antenna configurations and track durations affect anobservation. More information on simulating ALMA observations is available at:
http://casaguides.nrao.edu/index.php?title=Guide_To_Simulating_ALMA_Data.
The ALMA Observation Support Tool (OST) provides another method of simulating ALMA observations. The
OST provides a web interface to the CASA simulation code through which the user can specify observing
parameters and upload a FITS file with a model image, or select a model image from a pre-existing library.
The OST is available from the Science Portal.
The NAASC is also responsible for providing the ALMA user community with a complete, up-to-date spectralline catalog – Splatalogue. Splatalogue is an effort to collate and rationally organize existing spectroscopic
catalogues into a single resource for the astronomical community. The focus is on pure rotational and rovibrational transitions of astronomically relevant molecules for observations in the microwave and millimeterwave regions using telescopic infrastructure such as ALMA, VLA, and the GBT, amongst many others. As of
February 2016, Splatalogue contains over 8.1 million transitions from 1233 species and is updated regularly.
Splatalogue also features an interface that is Virtual Observatory (VO) compliant for interfacing with external
software or websites.
The main page for Splatalogue features the Basic search capabilities for the Splatalogue database. Use of the
Basic search is limited to:●●●●Common astronomically detected molecules and vibrational states, such as CO, H2O, methanol,hydrogen cyanide, and others.
Pre-defined “filtered” sets of molecules, such as those relevant to diffuse clouds, comets, planetaryatmospheres, etc.
Single molecules in the Splatalogue database outside those in the pre-defined categories.
User-defined frequency ranges as well as ALMA Bands 3-10 and lower state energy ranges.

In all cases, the only frequencies shown are those that are NRAO recommended. These frequencies are
typically selected from the most recently updated line list. Observed astronomical intensities for transitions
found in the Lovas/NIST database are also included along with the NRAO recommended frequencies. For
more information about Splatalogue and its use and functionality, visit http://splatalogue.online.

6.3 Preparing Your Observations
ALMA proposals are reviewed on their scientific and technical merit, and PIs are informed of the outcome of
the review process by email from the JAO. Programs eligible for scheduling are assigned a Contact Scientist,a member of the NAASC staff who provides a single point of contact for program support. NAASC staff and
the Contact Scientist work with the PI to review observing strategies and prepare Scheduling Blocks. After theobservations are made, the Contact Scientist can assist with questions related to data reduction. The mainmeans of interaction between PIs and NAASC staff is via the Helpdesk. For particularly complex observations,however, users may arrange a visit to the NAASC to prepare the observations (Section 6.5).
Observers do not travel to Chile or elsewhere to take part in the ALMA observations. Observatory staff
dynamically schedule ALMA observations, taking into account the weather conditions, instrument status,
availability of the targets, and proposal ranking.

96.4 Working with Your Delivered Data Products
The primary software package used to process ALMA data is CASA (Section 6.2 - http://casa.nrao.edu). Notein particular the CASA Guides link available from that site. The CASA Guides site provides a collection of data
reduction and imaging tutorials and step-by-step processing and analysis examples, including scripts forprocessing Science Verification data.
The challenge posed by storing and processing ALMA data is formidable. The NAASC hosts a copy of the ALMA
data archive and the NAASC site serves as the primary data access point for North Americans, and will provide
a backup of the archive in Santiago. Upon completion of the observations and initial data processing,investigators are notified and given instructions on how to download their data.
ALMA data are processed in two steps: first they are calibrated, and then imaged. Most ALMA data are now
calibrated and imaged using the ALMA Data Reduction Pipeline. In some rare cases, observatory or NA ARC
staff may prepare CASA scripts for calibration or imaging. Access to these data products are primarily available
through the ALMA Archive. The archive products include the raw data written in ALMA Science Data Model(ASDM) format and processed data products. The processed data includes:
●
●
●
●
●

QA2 report file which contains important information about your data including how your data were
processed.
FITS images
Calibration and imaging scripts (either pipeline- or manually-produced)
Calibration tables
Quality Assurance (QA) plots or the weblog if any part was processed by the ALMA pipelineo The weblog is an html-formatted collection of web pages containing diagnostic information
describing the pipeline run.
o A more detailed description of the pipeline and weblog can be found under the section ALMA
Science Data Tracking, Data Processing and Pipeline, Archive and QA2 Data Products at:https://almascience.nrao.edu/processing/documents-and-tools.

The fully-calibrated measurement set (ms) which includes only the science target data has been provided as
an additional "Added Value" service to North American PIs. Calibrated measurement sets are supplied with
all NA processed deliveries to the PI and (on request) to delegated co-PI or co-Is. Generally, calibrated data
provided to users are ready for science imaging. In a rare number of cases, however, users may get best
results by refining the calibration themselves, with assistance from NAASC staff (if desired).
The calibrated data are retained on disk for a period of ONE month. After that, for Cycles 1-4, users canrequest for re-generation of calibrated measurement sets via the ALMA Helpdesk. This service is restricted toprojects whose PIs have NA designated as their ARC for support. If the user is not a PI or delegated co-I, andis requesting calibrated measurement sets for public data, there will be a limit of FIVE such requests per
calendar year per requestor. For Cycles 5-present, users can request for re-generation of calibration
measurement sets at: data.nrao.edu. This service is provided to all users as long as the data is out of
proprietary period. If the data is still proprietary, only the PI or delegated co-(P)Is may make the request.
In addition to the calibrated target MS and QA2 information, we also provide the ADMIT products forinterferometric observations. ADMIT is an experimental ALMA development project which is designed to lookthrough science images and automatically provide line identification, moment maps, position-velocity
diagrams, etc. Please note that ADMIT products are not Quality Assured and line identification is only
performed for well-known chemical species. For more information about installing and using ADMIT on yourdata, please see the ADMIT CASA guide10Users are encouraged to visit the NAASC to get help with their data processing (Section 6.5). The NAASC has
computers with ample resources to reduce ALMA data, including powerful desktops and a cluster machine
connected to a high-speed LUSTRE file system. The NAASC also supports remote access to its cluster machine,which can be obtained by submitting a ticket to the helpdesk.
Short term or data reduction visitors will be assigned a temporary login and password to work on their data.
This short term visitor account can be used for a couple days up to a few (2-3) weeks. If additional time isnecessary, one extension can be made for this short term account for up to a few (2-3) weeks. After that, if
the user still needs additional substantial time to work on their data, they will be requested to use a long-term
NRAO account. This long-term account can be open for up to a year before renewal. To be able to qualify fora long-term NRAO account, the user must have the support of an NRAO scientific staff member. NAASC staff
will be more than willing to support long-term users working on their data on the NAASC cluster. NOTE NAASC resources are NOT the place for long term curation of user data products. Users will need to makeother arrangements for the long term storage of their data. To request remote access to the cluster, visit:https://science.nrao.edu/facilities/alma/docs/manuals/computing-resources/overview.
On the CASA website, there are recommendations for computing hardware required to process ALMA data
outside of the NAASC (visit https://casa.nrao.edu/casa_hardware-requirements.shtml).

6.5 Visiting the NAASC
The NAASC welcomes short-term visits to Charlottesville or Victoria, British Columbia from North American
investigators of successful ALMA programs or archival researchers for expert assistance with processing andanalyzing ALMA data. Visits for data reduction have to be requested at least one month in advance, and are
expected to last about a week. Novice visitors are required to be accompanied by an experienced investigator,e.g., a collaborator. Visitors will have access to an office and a computer to process their data. Investigators
who are requesting a short data reduction visit can apply to the NAASC for assistance with travel expenses.
To request a visit, send a ticket to the ALMA Helpdesk using the “Face-to-Face Support” category. More details
are available at: https://science.nrao.edu/facilities/alma/visitors-shortterm.
The NAASC also hosts approximately two Data Reduction Parties each year during which a group of 10-12 PIs
and their students visit the NAASC at the same time for assistance in data reduction and analysis. These parties
are similar to individual “face-to-face” support visits except that they also include lectures on ALMA data
packaging, the ALMA calibration and imaging pipelines, and advanced imaging analysis techniques, depending
on interest. The dates for these events are announced via the NAASC webpage and the NRAO eNews
newsletter.
Long-term visitors to the NAASC are also strongly encouraged, especially those interested in extending andoptimizing the capabilities of ALMA or improving the data reduction and imaging strategies. The length ofsuch visits are negotiable but can last between a few weeks to a year. Visit support can range from paying foraccommodation, per diem or travel costs, to salary supplements, as needed. More details are available at:https://science.nrao.edu/facilities/alma/community1/opportunities/visitorsprogram.

6.6 Publishing Your Results
Upon request, NRAO provides financial support for page charges to authors at U.S. scientific or educational

6.7 Promoting ALMA Science
The NAASC sponsors ALMA-themed science conferences on roughly an annual basis. A listing of previous
ALMA conferences and information on upcoming conferences is available at the following site:
https://science.nrao.edu/facilities/alma/workshops.
The NAASC also offers financial and logistical support to organize conferences and workshops hosted by thecommunity to promote ALMA science. This support is done twice a year. For more information and torequest support for your conference or workshop, please visit
https://science.nrao.edu/facilities/alma/community1/NAASC-Conference-and-Workshop-Support
NAASC activities and ALMA results are publicized in the NRAO eNews: http://science.nrao.edu/enews.
The NAASC is also involved in community outreach through special ALMA sessions at American Astronomical
Society and Canadian Astronomical Society meetings. At these sessions, we provide attendees with highlightsof recent ALMA science, describe the current status of ALMA, and give updates on the proposal submission
and data processing tools.
The Education and Public Outreach (EPO) team at NRAO works with investigators to publicize newsworthy
ALMA projects via news releases, videos, and other outreach products. In addition to providing expertise andadvice on outreach activities, the EPO team can develop images, graphics, and other visuals to promotescience results. To recommend a potentially newsworthy result or for questions, contact the NRAO
Department for Public Relations for ALMA (alma-pr@nrao.edu).

7 Working with the Community to Improve ALMA
The NAASC encourages involvement from the user community to develop and improve ALMA. The NAASC
periodically invites proposals from North American entities for studies or projects for potential inclusion in
the ALMA Development Plan. The primary aims are:●●●To give groups in North America the opportunity to propose ALMA upgrades that may later be
implemented as part of the ALMA Development Plan
To support the development of conceptual and detailed designs for ALMA upgrades, andTo encourage relevant long-term research and development

Development proposal calls are announced at: https://science.nrao.edu/facilities/alma/alma-develop/

8 Student Support
The NAASC supports student involvement in ALMA through the NRAO student programs. NRAO has a Summer
Student Program aimed at introducing undergraduate and graduate students to cutting-edge research. In
addition, a Student Observing Support Program funds graduate students working on eligible ALMA proposals.
Finally, a graduate Pre-Doctoral Program is available to give students the opportunity to conduct thesis
12research at NRAO sites under the supervision of an NRAO scientist. Details on the student programs areavailable at: http://science.nrao.edu/opportunities/studentprograms.shtml.

9 ALMA Ambassadors Postdoctoral Fellows Program
The ALMA Ambassadors Postdoctoral
Program provides training (and up to a
$10,000 research grant if based in theU.S.) to postdoctoral researchersinterested
in
expanding
their
ALMA/interferometry expertise andsharing that knowledge with their homeinstitutions through the organization of
ALMA proposal writing workshops. Eachyear beginning in Cycle 5, the NAASC
sponsors a group of selected postdocs totravel to Charlottesville, Virginia toreceive in-depth training in topics related
to ALMA proposal writing (includinginterferometry basics, ALMA sciencecapabilities, recent ALMA headlines, anduse of the Observing Tool) as well as
The 2020 Cycle 8 ALMA Ambassadors from the NAASC
guidance with speaking on these topics.
The postdocs then return to their home institutions or an agreed upon location to host 1-2 days proposal
preparation workshops in advance of the ALMA proposal deadline. More information on the ALMA
Ambassadorsprogram,includingupcoming
deadlines,
can
be
found

10 NAASC Participation and Initiatives in the Office of Diversity andInclusion (ODI)
The ODI National Astronomy Consortium (NAC - https://science.nrao.edu/opportunities/studentprograms/nac) is a program that had its roots in the NAASC and is led by the National Radio Astronomy
Observatory (NRAO) and Associated Universities Inc., (AUI) in partnership with the National Society of Black
Physicists (NSBP), and a number of minority and majority universities to increase the numbers of students
from underrepresented and underserved groups and those otherwise overlooked by the traditional academic
pipeline into STEM or STEM-related careers. The NAC Project Scientist position is held by NAASC staff andhandles most of the summer program development including organizing the weekly meetings and activities.
The National and International Non-Traditional Exchange (NINE - go.nrao.edu/NINE) Program is geared
towards enticing the best and brightest, both nationally and internationally, into high quality programs
designed to benefit the participant, each partnering location, and the radio astronomy community as a whole.
Finally, NAASC staff actively participate in mentoring students participating in the Louis Stokes Alliance for
Minority Participation (LSAMP - https://lsamp.virginia.edu/) program. The LSAMP program consists of 12
partner institutions, including the University of Virginia, and strives for diversification of the Science,
Technology, Engineering, and Mathematics (STEM) workforce, with an emphasis on increasing the number ofunderrepresented minority students earning baccalaureate degrees and matriculating to graduate school.
The LSAMP program targets early career undergraduates and work with staff on learning how to do scientific13research, especially involving synergistic research between astronomy and chemistry, in an eight week
summer program. The NAASC provides financial support for the NAC and NINE programs and supports NINE
hubs around the world. The NAASC works very closely with ODI on best practice for inclusion of all staff andin supporting safe spaces (http://www.nrao.edu/policy/diversity.shtml). NAASC management and leadership
all have “open door” policies especially when it comes to personnel issues. Finally, the NAASC is a major
corporate sponsor of the International Symposium on Molecular Spectroscopy and sponsors new initiatives
including the LGBTQIA+ reception.
