     64It should also be noted that the RFI detection script only flags RFI channels that persist throughout most of the
     65intervals that are examined. This behaviour can be changed by telling the script to flag each interval separately

     68The upshot is that at this point there is still some RFI present, ie. channel 513, during the first observations of
     691934-638.

     71The next step is to recalibrate the dataset again after removing most of the RFI.

     75Let's look at the calibration of 1934-638.
