Description: | It appears the datalogger program at SIRS/C1 was automatically updated, unbeknownst to
anyone, on 9/27/20041423GMT with an older program with incorrect UIR and DIR calibration
coefficients. The correct and incorrect cal coeffs for the UIR and DIR pyrgeometers during
this DQR period were:
