Flag Data for selected flag regions

Synopsis
flagdata(diskwrite, rowflag)

Description
Set flags for all regions marked using markflags(). 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.

Arguments

diskwrite		1 to write flags to the table on disk, 0 to set dummy flags
		Allowed:	Integer
		Default:	0
rowflag		1 to set a row-flag in addition to individual data flags, 0 to ignore row flags if individual flags exist
		Allowed:	Integer
		Default:	0

Returns
0 if flagging is successful, -1 otherwise

Example

# mark 2 flag regions on a multi-panel plot, one in panel 1 and one
# in panel 2. Then apply the flags and write to disk.
  tp.markflags(panel=1);
  tp.markflags(panel=2);
  tp.flagdata(diskwrite=1,rowflag=0);
