C221A Correlation Report
General information
- Session info: http://www3.mpifr-bonn.mpg.de/div/vlbi/globalmm/
- Station feedback: https://www3.mpifr-bonn.mpg.de/div/vlbi/globalmm/sessions/apr22/feedback_apr22.asc
- ALMA and LMT did not observe
- Mopra 86 GHz is linear polarized. Similarly, Yebes was inadvertently linear polarized for nearly the entire track.
- Release v1 is a release of all projects, without PolConvert of ML010A baselines to Mopra (nor to Yebes).
- Release v2 adds ML0101A 3mm with Mopra polarization converted to circular not with PolSolve+PolConvert (failed) but rather with QWP_ROTATE.py and a fixed 45 deg rotation and a fixed Mopra "RCP-LCP" offset taken from one calibrator scan

Notes
- PV joined late due to bad weather. The first scans were bad due to a setup problem. First good scan is 091-1415 No0265. Looks like the 3rd-last scan for PV, i.e. PV lost for most of this track.
- YS had technical problems in the beginning of c221a which were fixed after 091-0800 No0179. Missing quarter waves plates were inserted later. First good scan is 091-1415 No0265, the 3rd-last scan for YS.
- YS inadvertent linear-pol scans were not labeled as X,Y during correlation, but if PolConvert is indicated, could carry out relabeling on the existing visibility data prior to a PolConvert pass
- KU lacks fringes for the most of the track except for scans No0155-No0181
- Mopra is linear polarized (need PolConvert!) and had a different recording setup than scheduled, 2 x 2048 MHz at 85244.0 MHz USB.
- Mopra 20 scans of data lost at MPIfR due to VDIF conversion running while BeeGFS migration was ongoing, unfortunately no backup on transfer server
- Atca had a non-standard setup, 4 x 64 MHz USB at 86012.0 MHz and 86076.0 MHz
- Severe OpenMPI software issue, all of the 7 scans that have >=15 stations fail OpenMPI MPI_Init() with "num local peers failed". Fails also with a simple MPI Hello World program launched with the same mpi machinesfile. The MPI_Init() strangle succeeds when the machinesfile is first sorted alphabetically i.e. the exactly same nodes are used, merely started in different order. To correlate the 7 scans, had to reduce the nr of stations by dropping those stations that had bad data (Pv, Ys, Pt, La).
- GLT, Slack #c221, 01 Apr ~ 13 UT: "we observed M87 instead for scan 429, 435, 441, 446 as M87 has been low elevation", ~16 UT "GLT resumed the observations from scan 458. No snow, no problem so far."
- GLT, EHT 2022 obslog, scan 641 on 2013+370 and all later scans lost due to power outage
Frequency Setup
Mopra and GLT recorded wideband 2048 MHz, but did not have common scans in track A.
NOEMA recorded 1024 MHz of which 512 MHz are common with the majority of the GMVA array. Another 512 MHz are common only with GLT (38 scans Nn-Gl) and nominally with Mopra (but 0 scans Nn-Mp). These extra 512 MHz on Nn-Gl were not included in DiFX correlation.

FITS completeness (pclist)

Note that this FITS-IDI -based list does not show ML010A scans since they contain mixed circular-linear baselines due to Mopra, and this is not supported by FITS-IDI.
