JAO pipeline got stuck• Original idea: JAO do all pipeline, and ARCs manual reduction for
non-standard + alpha• Current plan: all of JAO + three ARCs do calibration+ imagingpipeline• ALMA-J computing prepares 8 more pipeline machines in addition to current 6pipeline machines• Daniel Espada is preparing software deployment, nine out of ten weresuccessfully pipeline calibrated and imaged.
• Typically ~3 days per SB including calibration and imaging. Most of themneeded a second pipeline run after flagging.
• Each of JAO, ARC is requested to add ~ 2 FTE more (EA accepted 1.33 FTEincrease)• In Japanese ARC, we squeeze 0.5 FTE from task assignment, 1 FTE from contract(from 2017 April), 0.5 FTE from Korean help

Masa Hayashi (DirectorsCouncil) asked to increase it. Finally more EA Grade C wereadded.

Problems…

Notification of problem affecting certain
ALMA data that used mosaic and offset
pointing observing modes (mostly Cy 1,2, one
example in Cy3)

• Apr 08, 2016
• The problem was introduced by the ALMA online system suchthat there was a small mislabeling of the position of each fieldrecorded in the data in these cases. This was due to aninconsistency between the way in which the online software
computed the coordinates that are stored in the field table of thedata and the way in which it computed the propagation delays
and antenna pointing coordinates.
• All data which were affected seriously have been re-delivered.
Proprietary clock was extended.

• OT and online software calculated offsets using Euler angles,
but Data Capture mistakenly used approximation of theprojection• RA = RA0 + dRA/cos(Dec0)• Dec = Dec0 + dDecfull-pol Cycle 3 data
• We found
an issue in the standard polarization calibration scripts used for thequality assurance. This issue yields a time-dependent excess of theamplitude in the calibrated cross-hand visibilities (XY and YX), whicharises due to failure to calibrate the X/Y gain amplitude ratio correctlyin the science target. As a result, the polarization image of the sciencetarget could be distorted.
• All PI were informed.
• JAO/ARCs are now investigating the impact to the final image
products caused by this issue and preparing a new script to fix it.
As soon as the script is ready, ARCs will reprocess the data and replace
the archive package. Th clock will be extended.

Discussion: Double Affiliation• How do you think Visiting Professor/Scholar to EA institution
from other region (NA/EU) submits ALMA proposal as an EAresearcher?

Discussion: Double Affiliation• Proposers Guide: ALMA policies prohibit multiple submissionsof the same proposal using different Executive affiliations.
• Users Policy: Multiple submission of the same proposal using
different Executive affiliations is not allowed.

• 4000 (+1000) hours of 12-m will be available, and3000 (+1200) hours on ACA.

Cycle 5 pre-announcement• Large Proposals may request more than 50 hours of 12m or
more than 150 (ß50) hours of ACA stand-alone, foreach program. Totally, up to 600 (ß450) hours of12m and 450 (ß270) hours of ACA stand-alone time
will be allocated to Large. Only standard modes (see below) arepermitted for Large.
• ALMA encourages the community to submit Regular
Proposals that request between 10 and 50 hours of 12mArray time.

Cycle 5 pre-announcement• VLBI: In addition to submitting an ALMA proposal, 3mm VLBI
programs must also submit a proposal to the GMVA VLBI by
1 February 2017. Additional information about GMVA will bemade available in mid-January 2017. Additional information
about NRAO/EHTC will appear in the ALMA Call for
Proposals (March 21).

Cycle 5 pre-announcement• Number of antennas• 43 (+3) antennas in the 12-m Array• 10 7-m antennas and 3 TP antennas• 12-m Array Configurations• 10 (ß9) configurations• Maximum baselines for the antenna configurations will vary from 0.25
km to 15 km; the planned configuration schedule will be released by1 February 2017 and published in the Proposer’s Guide• Maximum baselines of 3.6 (ß3.7) km for Bands 8, 9 and 10• Maximum baselines of 8.5 (ß6.8) km for Band 7• Maximum baselines of 16 (ß12.6) km for Bands 3, 4, 5 and 6

Cycle 5 Capabilities• 90-deg switching for sideband separation only for
TDM and wide FDM spw (1875 MHz bandwidth)àFor Band 9 &10 (DSB) it will effectively double the bandwidth from 8 GHz to
16 GHz per polarization from the DSB receivers.

Cycle 5 non-standard• Band 8, 9 & 10 observations• Band 7 observations with maximum baselines > 5 km
• Longest baseline configuration (16 km) in all Bands (Note in 2017
Jan: it will become standard)• All polarization observations• Spectral scans• Bandwidth switching projects (less than 1GHz aggregate bandwidths
over all spectral windows)• Solar observations (both Bands 3 and 6)• VLBI observations• User-specified calibrations

New in Cycle 5• Band 4 polarization*: Proposals will be accepted for Band 4
observations in all polarization modes, as for the other Bands.
• Band 5 observations: Proposals will be accepted for spectralline (12-m, 7m and Total Power arrays) and continuum (12-mand 7-m arrays) observations in Band 5. Polarization* will beoffered on the 12-m array, as for the other Bands.
* non-standard
