   Compression quality and size:   
      
   EFF - 'best' quality   
   EDN - 'medium'   
   ESF - 'thumbnail'

   Looks like all are P, except views of the Sun with pancam (F),   
   and EDL (also F).

   I suspect something about quality and size of the image.

   > M1 = ? (I don't think Mer-1, as that is Opportunity)
