FLDSIZE
Type:  Adverb (real array, 2 elements x 64 fields)
Use:   Sizes of a 2-dimensional image to produce or process; one pair of
       values is specified for each field.  The first element is usually
       called the X coordinate and measures the number of columns in the
       image.  The second element, the Y coordinate is a measure of the
       number of rows in the image.
Null Value: 0
       Null value assignment varies with verb or task although
       usually a value is required.
       IMAGR replaces FLDSIZE values of 0 with IMSIZE-10.
Tasks:
   IMAGR.......Wide-field and/or wide-frequency Cleaning / imaging task.
   PCCOR.......Corrects phases using PCAL tones data from PC table.
               FLDSIZE gives the 1st and 2nd tones to use by IF.
   SCIMG.......Full-featured imaging plus self-calibration loop with
               editing.
   SOUSP.......Fits source spectral index from SU table or adverbs.
               FLDSIZE gives source flux at frequency when not using
               the source table.  Normally set to 0.
Procedures:
   LINIMAGE....Build image cube from multi-IF data set.  FLDSIZE passed
               to IMAGR.
   MAPPR.......Simplified access to IMAGR.
