DOFLAG
Type: Adverb (scalar)
Use:  Controls the use of flagging or flagged data in tasks.
Tasks:
   BPEDT.........Interactive TV task to edit uv data based on BP
                 tables.  DOFLAG < 0 -> flag the BP table rather than
                 the UV data.
   CALIB.........Determines antenna calibration: complex gain
                 ABS(DOFLAG) determines the level of closure error
                 considered bad at the only non-robust solution or at
                 the last iteration of a robest solution.  If DOFLAG >
                 0, then flags are written to a flag table.
   OFLAG.........Uses on-line flag table information to write a flag
                 table.  Data are flagged if the score is >= DOFLAG.
   PRTAB.........Prints any table-format extension file.  DOFLAG>0 says
                 to also list flagged rows.
   PRTOF.........Prints on-line flag table information.  DOFLAG>0 says
                 to also list flagged rows.
   RFLAG.........Flags data set based on time and freq rms in fringe
                 visibilities.  DOFLAG>0 causes flagging to be done even
                 when DOPLOT>0.
   SYSOL.........Undoes and re-does nominal sensitivity application for
                 Solar data.  DOFLAG is used to stop flagging of the SY
                 and/or SN tables.
   TACOP.........Task to copy tables, other extension files.  DOFLAG>0
                 causes flagged rows to be copied.
   TYAPL.........Undoes and re-does nominal sensitivity application.
                 DOFLAG is used to stop flagging of the SY/TY and/or SN
                tables.
Procedures:
   IMSCAL........Large image self-cal with IM2CC and OOCAL.  DOFLAG>0
                 causes data with excessive closure error to be flagged.
   OOCAL.........Determines antenna complex gain with frequency-
                 dependent  models.  DOFLAG>0 causes data with excessive
                 closure error to be flagged.
   VLBAMPHC......Applies VLBARUN calibration to additional phase
                 stopping centers.  DOFLAG>0 causes RFLAG to be applied
                 to the data.
   VLBAPIPE......Applies amplitude and phase calibration procs to VLBA
                 data.
   VLBARFI.......Calibrates VLBA autocorrelations, writes out statistics
   VLBARUN.......Applies amplitude and phase calibration procs to VLBA
                 data. DOFLAG>0 causes RFLAG to be applied to the data.
   VLBAWIDE......Calibrates all VLA wide-band autocorrelations with
                 VLBARFI.
