General comments
Data products
- GMVA/24A-150, S. Xu, "Geodetic and Astrometric mm-VLBI" : provide MkIV/HOPS data in addition to FITS-IDI so that geodetic HOPS+NuSolve -based pipeline can be run
Metadata
- notes
- Session feedback: https://www3.mpifr-bonn.mpg.de/div/vlbi/globalmm/sessions/apr24/feedback_apr24.asc
- ALMA APP QA2 mostly missing, only received c241b deliverables

Correlation and HOPS notes
S. Xu from KASI provided improved coordinates for KVN Pyeongchang (Kc). These were used for rev2 correlation of c241b.
KVNPC Station Positions (Epoch: 2024.05.09-01:44:04):
- X Comp: -3149228782.15 <b1> 11.602 mm

PolConvert
Conversion uses PolConvert 2.0.7 that is part of DiFX 2.9.0. As with EHT 2022 and later it turned out APP QA2 packaging scripts and the PolConvert code repository are out of sync regarding the correct set of .ms tables to apply from the APP QA2 deliverables. Passively phased scans are also marked incorrectly in metadata ("no antennas" in passively phased scans).
Conversion of C241B used:
