tableplot.flagdata - Function

3.2.2 Flag Data for selected flag regions


Description

Set flags for all regions marked using tp.markregions(). The plot is automatically redrawn after applying flags.

If reduction TaQL functions such as sum,mean are used, flags corresponding to all accessed values will be modified. For example, with a measurement set table, flagging on the mean amplitude of stokes 1 and channels 1 to 5, given by ’MEAN(AMPLITUDE(DATA[1,1:5]))’ results in flags being set for all 5 accessed channels.

For a measurement set, by default, flags are set only for accessed channels and stokes when the DATA column is used. However all channels/stokes can be flagged for the marked flag regions by setting the corresponding row flag.
