NSA/MWR/C1 - Reprocess: calibration change
DataStreams:nsamwrlosC1.b1, nsamwrlosC1.a1
Description:
The thicker (1/2-inch) insulation was installed on the RF deck and the reference 
temperature was reduced from 50 C to 30 C to prevent thermal instability in winter. A change in 
the mixer temperature affects the instrument's calibration. A new calibration was 
automatically derived and applied after 1500 valid tip curves were acquired. During the period 
after the temperature was reset and before the calibration was updated, the previous 
calibration was used.
Suggestions: 
Reprocess the data with the new calibration.
