CLCORPRM Right-left phase differences for IFs BIF to EIF (as CLCOR) ---------------------------------------------------------------- RLCOR Task: This task will copy a uv-data set applying a right-left phase correction to as many as 20 IFs. Basically, this allows the CLCOR operation POLR to be applied to single-source files, The PCAL solutions (if any) in the appropriate AN table will be adjusted as is done by CLCOR. Adverbs: 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. SELBAND....Bandwidth of data to be selected. If more than one IF is present SELBAND is the width of the first IF required. Units = kHz. For data which contain multiple bandwidths/frequencies the task will insist that some form of selection be made by frequency or bandwidth. SELFREQ....Frequency of data to be selected. If more than one IF is present SELFREQ is the frequency of the first IF required. Units = MHz. FREQID.....Frequency identifier to select (you may determine which is applicable from the OPTYPE='SCAN' listing produced by LISTR). If either SELBAND or SELFREQ are set, their values override that of FREQID. However, setting SELBAND and SELFREQ may result in an ambiguity. In that case, the task will request that you use FREQID. SUBARRAY...Sub-array number to copy. 0=>all. BIF........First IF to include. 0 -> 1. EIF........Last IF to include. 0 -> max. 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. CLCORPRM...Right-Left phase difference in degrees to be applied to IF number BIF, BIF+1, BIF+2, ..., EIF (as many as 20 may be specified). If there are more than 20 IFs, the task will have to be run more than once, using the output of the previous pass as input to the current pass. ----------------------------------------------------------------
