Notes
- NOEMA LCP has no fringes, also not within +- 256 usec of NOEMA RCP fringes. Info from R. Garcia is that LCP related PolyFix was likely not synchronized correctly in C222A amid GPS receiver issues. There should be a fringe at an unknown large offset. Did a wider search in cross-pol autocorrelations till +-2560 usec, no fringes within that offset range. Already too large to correct in DiFX easily.
- BR has issues in LCP according to log
- GBT not scheduled
- VLBA outages and this track not observed at PT, KP, SC
- Pico polswapped in C222A but not in C222C
- Source K3-50A was scheduled in VEX/key for Ef-(Ys)-Nn-Pv for 15 sec pointings only, not to be included in project data exports

Polarization 3mm
Note, NOEMA LCP has no fringes in entire C222A due to undetermined too large clock offset in LCP.
