             (2) If phase rate corrections are to be done as part of the
                 calibration, then the integration time of the input
                 data must be given in APARM(2) to allow for an
                 amplitude correction to correct for the effect of time
                 smearing on the data.  Default is no correction.  There
                 is no time averaging of the output data.

This correction can be rather important for VLBI data.  But what do other
programs that apply calibration do?  They don't have the integration time.
