Notes: This table contains the result of an individual delay offset calibration.
CAL_DATA_ID
Calibration data identifier
CAL_REDUCTION_ID
Calibration reduction identifier
ANTENNA_ID
Antenna identifier
SPECTRAL_WINDOW_ID
Spectral window identifier. A value of -1 indicates the row is valid for all spectral windows.
START_VALID_TIME
Start time of result validity period
END_VALID_TIME
End time of result validity period
DELAY_OFFSET
The measured delay offset, for the identifiers above. This affects the antenna in row AntennaID, relative to the antenna RefAntennaID in the ANTENNA table.
DELAY_ERROR
Uncertainty in DelayOffset
CROSS_DELAY_OFFSET
The measured cross-polarization delay offset. It is valid for all antennas (AntennaID = -1).
CROSS_DELAY_ERROR
Uncertainty in CrossDelayOffset
REF_ANTENNA_ID
Refers to the relevant row in ANTENNA Table, for the reference antenna.
