To run streaks:
 %> bin/immask streaks DECam_00226647_47.fits.fz clean_DECam_00226647_47.fits  --bkgfile DECam_00226647_47_bkg.fits.fz 
To run cosmic rays:
 %> bin/immask cosmics DECam_00226647_47.fits.fz clean_DECam_00226647_47.fits 
To run everything:
 %> bin/immask all     DECam_00226647_47.fits.fz clean_DECam_00226647_47.fits  --bkgfile DECam_00226647_47_bkg.fits.fz 

To generate an fpacked output image:

 %> bin/immask all DECam_00226647_47.fits.fz clean_DECam_00226647_47.fits.fz --bkgfile DECam_00226647_47_bkg.fits.fz --compress
