ATCA had some problems with caobs. At around 0018 UT on 24/02/2019, assist complained of no recent data from the correlator. But the antennas kept tracking through 0022 UT or so. Then they went idle. Jamie fixed caobs by 0026 UT. The same thing then happened at 0148 UT, and was fixed within 1-2 minutes, and finally it fell over at 0152 UT and was fixed by 0159 UT. There may or may not be data available from those periods.
Also, some phase drifts on ca03 from around 0037 until the next rephasing ~40min later, so the phasing up may have been slightly less good in that period.
