TPTCSPNT_080415 - Azimuth track mapping

The Plan: slow azimuth tracks, plus steps in azimuth.

The weather was unexpectedly clear and windless. Temperature: 10:50PM 30F, 04:45AM 21F (from operator log) Forecasts had predicted cloudy conditions with possible snow, so the high frequency observers gave up the time.

Observing Log

  Setup as if for X-band.
  - Position to az,el = 0, 50
  - scheduling block "AzStepsCW.sb" : step by 45 degrees, wait 2 minutes, repeat.
  Scans 1-8 : 2-min tracks at AZ=0, 45, 90, 135, 180, 225, 270, 315

  - sched block "AzScansBoth.sb"
  Scan 9 : slow scan from az = 362 to -2 at 150 arcmin/min   2008_04_15_04:38:47.fits
  temperatures at start: -2.2, -3.6, -3.7 C  (weather1, weather2_temp_1, weather2_temp_2)

  Scan 10 : slow scan from az = -2 to +362                   2008_04_15_07:04:43.fits
  temperatures at end:  -5.5 -6.8 -7.2 C

  - sched block "AzStepsCCW.sb"                 first one =  2008_04_15_09:31:00.fits
  Scans 11-18 : 2-min tracks at 360, 315, 270, 225, 180, 135, 90, and 45.
