The Calibration Parameters share the following items:
-
Calibration Type Parameters name
: A user settable name, to be used as a mnemonic.
-
Cycle Time
: How often this calibrator should be observed within the observing script of the SB (may be overridden when observing).
-
Default IntegrationTime
:A Default integration time on this calibrator (may be overriden when observing)
-
Data Origin
: Data source to use when analysing results from this calibrator target when observed at the RepresentativeFrequency with the RepresentativeBandwidth Source can be channel, average, cross of auto correlation, wvr, etc.
-
Sub Scan Duration
: The subscan duration must be a multiple of the integration duration. This is the number of seconds the subscan will last. When this duration ends, data stops flowing from the CDP.
-
Adjust subscan duration to a correct value
: Ensure that the subscan duration is a multiple of the integration duration.
In addition, the PolarizationCal Parameter has the folowing item:
-
Desired Polarization accuracy
: The desired calibrated accuracy resulting from this calibration.
In addition the PointingCal Parameter has the following items:
-
Desired Accuracy
: The desired calibrated accuracy resulting from this calibration
-
Pointing Method
: Method to be used for the calibration
-
Maximum Elapsed Time
: Maximum time allowed to achieve this accuracy.
-
Excursion
: Maximum outwards excursion during the calibration.
