Optionally, it will write an output file with all of the printed correlators flagged as bad. Data are printed and deleted only if their mean exceed some multiple of the expected errors in the mean or if their rms is excessive. Adverbs: USERID.....Input UV file owner number. 0 => logon user, 32000 => any user. INNAME.....Input UV file name (name). Standard defaults. INCLASS....Input UV file name (class). Standard defaults. INSEQ......Input UV file name (seq. #). 0 => highest. INDISK.....Disk drive # of input UV file. 0 => any. OUTNAME....Output UV file name (name). Standard defaults. OUTCLASS...Output UV file name (class). Standard defaults. OUTSEQ.....Output UV file name (seq. #). 0 => highest unique OUTDISK....Disk drive # of output UV file. 0 => highest with space for the file. DOOUTPUT...> 0 => write the flagged output file. Else just do the printing. DOCRT......False (<= 0) use the line printer if OUTPRINT = ' ' else write named OUTPRINT file only. True (> 0) use the terminal interactively. The task will use the actual terminal width as a display limit unless 72 < DOCRT < width. In that case, the display limit will be DOCRT characters. OUTPRINT...Disk file name in which to save the line printer output. ' ' => use scratch and print immediately for interactive jobs - batch jobs use OUTPRINT = 'PRTFIL:BATCHjjj.nnn' (jjj= job #, nnn = user #). When OUTPRINT is not blank, multiple outputs are concatenated, and the file is not actually printed. CHANNEL....Starting spectral-line channel number 0 => 1. UVRANGE....Print and flag only data having projected spacing between UVRANGE(1) and UVRANGE(2) in kilowavelengths. 0 => all. TIMERANG...Start time: TIMERA(1-4) = day, hour, minute, second Stop time: TIMERA(5-8) = day, hour, minute, second CPARM......CPARM(1) Print and flag IPOL correlators having mean > CPARM(1) * the expected error in the mean. 0 => 4. CPARM(2) As CPARM(1) for cross polarizations. CPARM(3) = IPOL cutoff level in the rms (Jy). Print and flag all data having rms > CPARM(3). 0 -> 1E9. CPARM(4) As CPARM(3) for cross polarizations. CPARM(5) = flux of unpolarized point source at the origin to be subtracted before summing things. ----------------------------------------------------------------
