In this section I will discuss the task CALIB , which is the work-horse of the calibration package (apart from yourself). CALIB determines the antenna gains as a function of time from the calibrator source(s). It determines the gain solutions only at the times of the calibrator(s). These gains are then interpolated to the times of your program source(s).
I remind you that a full gain and polarimetric calibration can only be made with MIRIAD. Please refer to § 4 for advice on the compromise you are making by calibrating your ATCA data in AIPS.
