CCSEL: Select significant CC components
INNAME Main input file (name).
INCLASS Main input file (class).
INSEQ 0.0 9999.0 Main input file (seq. #).
0 => high
INDISK 0.0 9.0 Disk unit #. 0 => any
INVERS Input file version no.
OUTVERS Output file version.
BCOUNT 0.0 99999.0 Beginning row to copy
ECOUNT 0.0 99999.0 Last row to copy: 0 => end
SCALR1 Radius to sum (asec)
CUTOFF Minimum summed flux
< 0 -> min absolute value
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
There is currently a limit of 1,000,000 components, using
CCMRG can help reduce the number.
Note: the time required to run increases quadratically
with the number of components.
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
CUTOFF......The minimum acceptable summed flux. If the value
is negative then summed fluxes with magnitudes
larger than ABS(CUTOFF) are accepted.
