Subject:
HFE/MWRHF/M1 - Calibration updates
DataStreams:hfemwrhfM1.b1
Description:
The MWRHF calibration algorithm updates the calibration parameters every time a new 
successful tip curve is acquired. 

This results in small jumps (1-2 K) in the brightness temperatures each time calibration 
is updated. During times of frequent calibrations the data appear discontinuous with short 
data segments interrupted by small jumps.
Measurements:hfemwrhfM1.b1:
  • Sky brightness temperature (150 GHz)(tbsky150)
  • Sky brightness temperature (90 GHz)(tbsky90)

Subject:
HFE/MWRHF/M1 - Elevated noise in 150 GHz data
DataStreams:hfemwrhfM1.b1
Description:
The noise level of the 150 GHz channel was about 4 times higher than expected, likely due 
to failure of the noise diode.  Disregard the 150 GHz data.
Measurements:hfemwrhfM1.b1:
  • Sky brightness temperature (150 GHz)(tbsky150)
