iminfo -- Print an instrument-specific header for a list of HST images, or a general header for a list of IRAF images.
The iminfo task will print general header information and instrument-specific information, based on the value of the image header keyword INSTRUME. If INSTRUME cannot be found in the image header, or its value is something other than "ACS", "FOC", "FOS", "HRS", "HSP", "NICMOS", "STIS", "WFPC", or "WFPC2", then only a general header will be printed.
Note that for ACS, NICMOS, and STIS files it is necessary to specify a FITS extension on the input file name(s). For these files it is best to specify either a science image extension (extname = "SCI") or extension number 1 (which is usually a SCI extension).
