    44Investigation of bandpass variations using the long observations of 1934-638 done during scientific commissioning.

    6 In order to use the 1934-638 data from this data set it is important to flag out the following visibilities in order to fix a problem associated with the time-stamps jumping forward a day and then back again:
     6This data set has an unusual fault - the time stamps on some records are incremented by 86400 seconds (instead of 0 or 1). This causes miriad to complain about the visibilities being out of time order; this is not the problem, the problem is the timestamps are off by 1 day.
     7To hack out the problem records, run {{{uvflag}}} with these selections:
     8
    79{{{
    8   select=visibility(91993,93432)
     10   select=visibility(91993,93432)
    911   select=visibility(83353,84792)
    1012   select=visibility(63361,64800)
