Introduction
1.1

About the Multi-wavelength Data Analysis System

National Astronomical Observatory of Japan (NAOJ) Astronomy Data Center (ADC) operates the Multiwavelength Data Analysis System (MDAS) which is an open-use computing system. MDAS is constructed
to analyze astronomy data at any wavelength. More than 100 software packages installed in the system
support data reduction and analysis of astronomy data observed by various telescopes.
MDAS consists of interactive data analysis servers, MDAS terminals, and its peripherals. Users accessan interactive data analysis server with SSH connection and analyze data. MDAS terminals located in the
Subaru building open-use room and ALMA building room 101 on the NAOJ Mitaka campus can be used
for connecting to an interactive data analysis server.
MDAS is a computing system for “analytic researches of astronomical observation data”. For those whowant to perform calculations related to the simulation astronomy, please use computing systems operated
by Center for Computational Astrophysics (http://www.cfca.nao.ac.jp).

How to install If you want to use AIPS, you have to install AIPS by youself. In the old MDAS, AIPS
was installed on the system. However, the policy was changed because only 8 AIPS IDs were available peruser.
The following is the instructions for installing AIPS 31DEC23. Note that the dependencies XTerm andncurses-compat-libs are installed on the system.

Information from East Asia ALMA Regional Center (EA ARC) Note that due to the OS upgrade(Rocky Linux 8), CASA version compatible to OS is limited to CASA 6.5.4-9(Python3.8), which is used for
the ALMA Cycle 10, or later. Please also refer the following page to check the compatibility between the
OS version and CASA version.
• https://casadocs.readthedocs.io/en/stable/notebooks/introduction.html#Compatibility
Data obtained after May 10, 2021 (later part of ALMA Cycle 7) and the former data sets which were
processed with the pipeline can be reconstructed using CASA 6.5.4-9(Python3.8). Please refer the link
below for further information. Note that manually calibrated MS data sets require same CASA version
used for the QA2. Please refer further information in the following page.
• https://almascience.nao.ac.jp/processing/science-pipeline
QA2 report tells us whether the calibration has been done by pipeline and manual processing. Pleaserefer following document for how to check the QA2 report.
• https://almascience.nao.ac.jp/documents-and-tools/cycle10/alma-qa2-data-products-forcycle-10
In addition, East Asia ALMA Regional Center (EA ARC) oﬀers to deliver the calibrated MS data.
With this service, you will be able to access older data sets (data taken before ALMA Cycle 7) stored in
the ALMA archive. Please use the template in the following page to submit your request to the ALMA
Helpdesk, if necessary. Depends on the demand from users, it may take some time to deliver the calibrated
data set.
