Kaike Pan
---- Observing Plan ----
Complete post-shutdown apogee calibrations and ventilate the telescope
---- Observing Summary ----
Lots of rain tonight. I ventilated the telescope for three hours when humidity is low enough and not raining.
APOGEE post-shutdown calibration was completed. Here are files:
30X100-read darks: apRaw-53540002-apRaw-535400016 and apRaw-53540002 - apRaw-535400016
30x25-read internal flats: apRaw-53550018 - apRaw-53550047
10x30-read quartz flats in SparsePak configuration: apRaw-53550048 - 57
2 AB pair of 12-read THAR exposures on sparsePak. Add "test" in OBSCMT:
apRaw-53550059, 12, A, ArcLamp
apogee.expose=apRaw-53550060, 12, B, ArcLamp
apogee.expose=apRaw-53550061, 12, B, ArcLamp
apogee.expose=apRaw-53550062, 12, A, ArcLamp
2 AB pair of 40-read UNE exposures on sparsePak. Add "test" in OBSCMT:
8:40:14  apogee.expose=apRaw-53550063, 40, A, ArcLamp
08:47:28  apogee.expose=apRaw-53550064, 40, B, ArcLamp
08:54:38  apogee.expose=apRaw-53550065, 40, B, ArcLamp
09:06:12  apogee.expose=apRaw-53550066, 40, A, ArcLamp
2 pairs of 30-read FPI exposure on sparsePak. In the OBSCMT, write down "FPI sparsepak":
9:20:36  apogee.expose=apRaw-53550067, 30, A, ArcLamp
09:29:52  apogee.expose=apRaw-53550068, 30, B, ArcLamp
09:37:54  apogee.expose=apRaw-53550069, 30, B, ArcLamp
09:44:58  apogee.expose=apRaw-53550070, 30, A, ArcLamp
The rotator was moved from 0 to -185, then to 365 twice. I will check the data later.
