If you are using a later version of CASA and this is the most recent available guide, then you should be able to use most, if not all, of this tutorial. == Overview == This CASA Guide describes the procedure for calibrating a phase-referenced VLBA observation of two masers in W3OH and W3IRS5. The data were taken specifically for this tutorial. The observation made use of th..."

The top row shows the data before the TFCrop flags are applied. The bottom row shows what the data will look like after the TFCRop flags are applied. Notice that TFCrop is aggressively flagging the edge channels. current
