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. ----------------------------------------------------------------
