Any "new" IFs added will have all their values blanked, data from "deleted" IFs will be lost. Note: UVCOP is a better way of selecting IFs. The intent of this task is to either add an IF axis into data sets which do not contain one or to change the dimensionality in data sets which do. This is normally not necessary but may be needed if a particular task insists on having an IF axis or in order to combine datasets (DBCON) with different IF axis dimensions. Adverbs: INNAME.....Input UV data file INCLASS....Input UV data file (class). Standard defaults. INSEQ......Input UV data file (seq. #). 0 => highest. INDISK.....Input UV data file disk drive #. 0 => any. OUTNAME....Output UV data name. OUTCLASS...Output UV data class. OUTSEQ.....Output sequence number. OUTDISK....The disk drive # of output images. 0 => highest NPOINTS....The number of output IFs 0=> 1. FQCENTER...> 0 => Change frequency axis reference pixel to Nchan / 2 + 1 else => do not change reference pixel BADDISK...This array contains the numbers of disks on which it is desired that scratch files not be located. BADDISK has no effect on input and output data. ----------------------------------------------------------------
