1. OVERVIEW.

   Script easymosaic.pl should be used to quickly create 
   browse quality mosaics (quick and dirty).
   Script easymosaic.pl uses no namelists. 
   The only input is either a list of input images:
       easymosaic.pl ListofImages.lis
   
   or a wild card path:
       easymosaic.pl SPITZER.1*bcd.fits.

   It produces four mosaic images:
   mosaic.fits, the coverage map mosaic_cov.fits,
   the uncertainty mosaic based on the data scatter mosaic_std.fits,
   and the median mosaic median_mosaic.fits.

   The results never get overwritten. The output directory
   is named mosaic:<date>:<time>, e.g. mosaic:28Mar2005:9h11m13s
	
   The options, normally set in the namelist for mosaic.pl, are hardcoded in easymosaic.pl. 
   Running on the 28th of March, 2005, at 9:11:13 am the following 
      easymosaic.pl  ListofImages.lis
   is equivalent to running mosaic.pl with the following namelist:

		have_uncertainties = 0
		compute_uncertainties_internally = 0 
		run_fiducial_image_frame = 1
		run_mosaic_interp = 1
		run_mosaic_coadder = 1
		run_mosaic_combiner = 1
		run_median_mosaic = 1

		NICE = 0
		verbose = 1
		delete_intermediate_files = 0

		MOSAIC_PIXEL_RATIO_X = 1
		MOSAIC_PIXEL_RATIO_Y = 1

		OUTPUT_DIR = mosaic:28Mar2005:9h11m13s
		COMBINER_DIR =  ./

		&FIDUCIALIMAGEFRAMEIN
			CROTA2 = -30.,
		&END

		&MOSAICINTIN 
			INTERP_METHOD = 3,
			GRID_RATIO = 1,
		&END

		&MOSAICCOADDIN
		&END
