CAL_DATA_ID
Calibration data identifier
CAL_REDUCTION_ID
Calibration reduction identifier
ANTENNA_ID
Antenna identifier
FEED_ID
Feed identifier
FREQUENCY_RANGE
Frequency range in which the result is valid. Note that the list of spectral windows corresponding to this frequency range must correspond to a single receiver band, this band being known via RECEIVER_ID which is (are) in the data section of the FEED table.
START_VALID_TIME
Start time of result validity period
END_VALID_TIME
End time of result validity period
UNCORR_APERTURE_EFF
Result in terms of antenna aperture efficiency, without using atmospheric pathlength correction (WVR)
CORR_APERTURE_EFF
Result in terms of antenna aperture efficiency, using atmospheric pathlength correction (WVR)
APERTURE_EFF_ERROR
Statistical error of the aperture efficiency determination (statistical)
CORR_VALIDITY
Deduced validity of atmospheric pathlength correction (WVR)
