Notes: This table contains the result of a single phase calibration scan. Nr is the number of receptors as specified in the FEED table.
CAL_DATA_ID
Calibration data identifier
CAL_REDUCTION_ID
Calibration reduction identifier
ANTENNA_ID
Antenna identifier (for antenna 1 and antenna 2)
FEED_ID
Feed identifier (associated to antenna 1 and to antenna 2)
FREQUENCY_RANGE
Frequency range used to determine the result. 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_PHASE_RMS
Phase RMS, computed without using atmospheric pathlength correction (WVR)
CORR_PHASE_RMS
Phase RMS, computed using atmospheric pathlength correction (WVR)
STAT_PHASE_RMS
Phase RMS due to thermal fluctuations only.
CORR_VALIDITY
Deduced validity of atmospheric pathlength correction (WVR)
