Subject:
NSA/GVR/C1 - Instrument calibration
DataStreams:nsagvrC1.a0, nsagvrC1.b1
Description:
During the period of time specified, the instrument was undergoing calibration. The 
antenna pointed constantly to a hot load placed on the instrument window. All brightness 
temperatures during this time have temperatures > 300 K.
Measurements:nsagvrC1.b1:
  • Unfiltered 183.3 +/- 3 GHz sky brightness temperature(tbsky3u)
  • Physical temperature of thermoelectric cooling plate(temp_thermoelectric_cooling_plate)
