Basic Information on fgflag
Purpose: Apply an AIPS flagging table to visibility data.
Categories: calibration, uv analysis
FGFLAG is a Miriad task which flags visibility data according to
the contents of an AIPS flagging table (``AIPS FG'' tables).
These flagging tables can be created by AIPS, and transfered by
FITS file. If a visibility FITS file read using Miriad task ``fits''
contains AIPS FG tables, they will be copied (without applying them)
to the output Miriad data-set. FGFLAG can then be used to apply these
flagging tables to the data.
Note: The flagging tables, and information needed to apply them, is
not copied by any Miriad tasks such as ``uvaver'' or ``uvcat'',
nor do any other Miriad tasks interpret them. It is best to apply
the flagging table soon after loading in a FITS file.
Note: The information to flag based upon polarization is lost by
task ``fits''. Consequently fgflag flags without regard to
The input visibility data-set to flag. No default.
Normal uv selection. This selects which data to apply the flagging
table to. Window and amplitude selection are not allowed.
The default is to apply the flagging table to the entire data-set.
When there are multiple flagging tables in the data-set, this gives
the table number to apply. The default is the highest versioned
