Algorithm

inthist is a perl script which does the following:

  1. Read input parameters and check for errors

  2. Run the FTOOLS task farith to flat field the input images

  3. Run the F90 module intmakehist:

    module intmakehist
    
         Read input flatfielded images and parameters
    
         Open output Post Script file
    
         Foreach (input image){
    
             Rebin to specified binsize
    
             Estimate histogram mean and variance using sigma clipping
    
             Compute optimal histogram binsize and display range based on
             mean and variance 
    
             Build and plot intensity histogram
         }
     
         Close Post Script file
       
    end module intmakehist
