1. Flux Calibration and Extinction Correction
Next: Airmass Calculation Up: Flux Calibration Previous: Flux Calibration . To calibrate the chromatic response, observations of a standard star (preferably more than one) are needed, for which the absolute fluxes are known. The spectral response curve of the instrument can then be determined with the command RESPONSE/LONG , and absolute fluxes for the objects of interest are obtained with CALIBRATE/FLUX . ...

4. An alternative approach to calibration
... This calibration approach is recommended when dealing with high frequency data from the old ATCA correlator, especially at 3mm wavelengths. ... The approach described here exploits the dual frequency bands that were available with the old correlator. ...
