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
