Isophotal analysis with deblending

This example performs isophotal analysis with deblending of overlapped images on a frame containing a mixture of stars and galaxies. The results are then plotted on a hardcopy device.

   # pisafind
   IN - NDF containing input image > frame
     Analysing whole image
   MINPIX - Minimum pixel size for images (typically 4-16) > 6
   METHOD - Intensity analysis ( 0=Isophotal, 1=Total, 2=Profile ) > 0
     Estimated background level =   492.2
     Background standard deviation =     7.4
   BACKGROUND - Background (global sky) value /492.17/ >
   THRESH - Threshold for analysis (data units) > 11.5

     Total number of positive images = 141
     The results have been written to pisafind.dat
         and pisasize.dat

   # pisaplot
   RESULTS - File of PISAFIND parameterised data /@pisafind/ >
   DEVICE - Name of graphics device > postscript_p
