    • Pv lost most scans to wx, good scans are No0030 095-0240 till No0039 095-0345 inclusive
    • GLT observing logs on EHT 2022 wiki note high wind speeds 6-13 m/s throughout C221E, light snow from 06:06 UT, heavy snowfall from 08:04 UT
    • ATCA has around 0.09 usec offset between IFs, PI should fringe-fit accordingly
    • No GLT fringes in this track in releases v1, v2
    • Tuning error at GLT found 03/2023, they were unknowingly 63 MHz off after C221A, fixed in release v3
    • Recorrelation of GLT--Mopra in scan No0074 on M87 with full 2048 MHz bandwidth on that baseline: no GLT fringes in v3 either, just Mopra-KVN fringes i.e. Mopra was fine.either-only in track C221A
