CLIC\SET AMPLITUDE [ABSOLUTE|RELATIVE] [SCALED|UNSCALED]
This command controls which scaling factor is applied to the data for
plotting and writing in the output table, in subsequent PLOT and TABLE
- ABSOLUTE means that the relative amplitude calibration is not ap-
- RELATIVE means that the relative amplitude calibration, as deter-
mined with SOLVE AMPLITUDE, and stored with STORE AMPLITUDE, is ap-
- SCALED means that the absolute amplitude is divided by the source
flux; SCALED is only used for the command SOLVE AMPLITUDE.
- KELVIN|JANSKY indicates the unit in which the amplitude are dis-
played: either Kelvins (in main-beam brightness temperature) or Jan-
SET AMPLITUDE ABSOLUTE forces SET AMPLITUDE KELVIN since the uncalibrat-
ed data are measured in Kelvins. With SET AMPLITUDE RELATIVE, the ampli-
tudes are in Janskys, since a calibrator of known flux has been used for
reference. If the default is overridden (SET AMPLITUDE ABSOLUTE JANSKY
or SET AMPLITUDE RELATIVE KELVIN), conversion factors (=antenna effi-
ciencies) are taken from the scan headers; these factors may be deter-
mined by SOLVE FLUX and stored by STORE FLUX.
SET AMPLITUDE ANTENNA|BASELINE switches between Antenna-based and Base-
line-based amplitude calibrations. This switch will be active for SOLVE
AMPLITUDE (calibration curve determination), STORE AMPLITUDE (calibra-
tion curve storing operation), and SET AMPLITUDE RELATIVE (application).
Both baseline-based and antenna-based calibration curves may be stored
alongside in the data header, independently of each other. Using SET AM-
PLITUDE ANTENNA is recommended.
