Prepare an input file for the profiles.sh code.

 
%  profiles_prep --help  
usage: profiles_prep a.fits [-v] [-h] [-r 100.0] 
Additional options: 
     -v  = print verbose comments and run in debug mode 
     -h  = show a help file and then exit 
     -r  = max radius for apertures (rmax=0.0 to use region ds9 region to defibe)  

EXAMPLES:
% ls
