Observations
Pointing coefficients for Ants 4, 6, and 9 were updated today.
The schedule has a new line just after each SOLPNTCAL, GAINSOLPNT, which
extends the SOLPNTCAL scan to add a GAINCAL calibration. After some tests to
check that it is working, the GAINCALTEST will be "retired". Note that
the GAINSOLPNT line will not start a new scan, but will continue the preceding
SOLPNTCAL.

Tohban notes for Wednesday Apr 24:
Ant 4 FE Temp is sometimes out of range--no solution yet.
Ant 5 has low VPOL power probably due to DCM issue
Ant 7 has no VPOL power probably due to a failed optical link. HPOL also down.
Ant 10 has no VPOL power probably due to a failed optical link.
Ant 10 FE Temp reporting bad temperature due to failed sensor.
Report problems here:
The schedule was very weird today, stowing the array until 15:10 UT and then
going directly to a calibrator. We missed a flare as a consequence. I
decided to skip the calibration and got the array on the Sun at 14:40 UT.
