AIPS views CALCODEs as a property of the source not the<br />scan. Therefore you cannot have one CALCODE on a source<br />for some scans and a different CALCODE for the same source<br />for other scans. The JVLA allows this for some reason but I<br />fail to understand why all scans of a source should not be used<br />for phase calibration when some are so used. The same applies<br />to the bandpass usage. Either a source is a good phase calibrator<br /> or it is not, it is either a good bandpass calibrator or it is not.<br />Note that BPASS and CALIB allow you to specify time ranges<br />should you really insist on separating your data in this way.<br /><br />Eric Greisen
