HELP SECTION
SDCAL
Task: Apply single-dish calibration to the input data, writing a
calibrated and flagged output data set.
Adverbs:
INNAME.....Input SD file name (name). Standard defaults.
INCLASS....Input SD file name (class). Standard defaults.
INSEQ......Input SD file name (seq. #). 0 => highest.
INDISK.....Disk drive # of input SD file. 0 => any.
TIMERANG...Time range of the data to be copied. In order: Start day,
hour, min. sec, end day, hour, min. sec. Days relative to
reference date.
STOKES.....The desired Stokes type of the output data:
'I','V','Q','U','IQU','IQUV','IV','RR','LL','RL','LR',
'HALF' (=RR,LL), 'FULL' (=RR,LL,RL,LR)
BIF........First IF to copy. 0=>all.
EIF........Highest IF to copy. 0=>all higher than BIF
BCHAN......First channel to copy. 0=>all.
ECHAN......Highest channel to copy. 0=>all higher than BIF
SUBARRAY...Subarray number to copy. 0=>all.
DOCALIB....If true (>0) then calibrate the data using information in
the specified calibration (CS) table.
GAINUSE....Version number of the CS table to apply. 0 => highest.
FLAGVER....Specifies the version of the flagging table to be applied.
0 => highest numbered table.
< 0 => no flagging to be applied.
OUTNAME....Output SD file name. Standard defaults.
OUTCLASS...Output SD file name (class). Standard defaults.
OUTSEQ.....Output SD file name (seq. #). 0 => highest unique
OUTDISK....Disk drive # of output SD file. 0 => highest with
space for the file.
APARM......Control information:
APARM(1) > 0 => all frequency channels in all IFs will be
averaged in the output. <= 0 => no averaging.
APARM(3) > 0 => drop the subarray code from the visibility
records.
BADDISK....A list of disks on which scratch files are not to be
placed. This will not affect the output file.
