HELP SECTION

CCSEL
Type:  Task
Use:   CCSEL is intended to filter out weak isolated CLEAN
       components which can cause a signifigant bias.
       This task sums the flux of all components within a
       specified distance of each component and then selects
       those components for which this sum exceeds a specified
       threshold.   The fluxes of the components are not
       modified.
          There is currently a limit of 10,000 components, using
       CCMRG can help reduce the number.
          Note: the time required to run increases quadratically
       with the number of components.
Adverbs:
  INNAME......Main file name (name).       Standard defaults.
  INCLASS.....Main file name (class).      Standard defaults.
  INSEQ.......Main file name (seq. #).     0 => highest
  INDISK......Disk drive # of image.       0 => any
  INVERS......Input extension file version #.
  OUTVERS.....Output extension file version #. 0=>make new
  BCOUNT......Beginning row number to be included .
  ECOUNT......Last row number included.  0 = highest.
  SCALR1......The radius in arcseconds within which to sum
              components.
  CUTOFF......The minimum acceptable summed flux.  If the value
              is negative then summed fluxes with magnitudes
              larger than ABS(CUTOFF) are accepted.
