SELF_TIMES

        Variable  length  array specifying the integration time (in seconds) for
        each loop of the self-calibration process.

        At NOEMA, 45 sec is the normal minimum integration  time.  Depending  on
        Signal  to  Noise,  you  may need to have this longer, e.g. 120 sec. For
        several loops, start with a longer value, and decrease only at the end.

        At ALMA, the minimum integration time is 6 sec. At VLA, this may  be  as
        small as 1 sec.

        It  is recommended to use the same integration time for the last two it-
        erations, to simplify the interpretation of the results and of the SELF-
        CAL SHOW display.

        This variable length array can be resized using the LET /RESIZE command.
        For example
            LET SELF_TIMES 180 90 45 /RESIZE
        will lead 3 self-calibration loops (if SELF_TIMES and  SELF_MINFLUX  are
        also of size 3) with decreasing integration times.
