                     AIRSAR EMBEDDED HEADER FORMAT

    An AIRSAR data file contains one or more header records embedded at
the beginning of the file.  These records are composed of 50-byte ASCII
text fields in a keyword=value format.  The first header record (also
called the "new" header in the SYNTHESIZE program) has the following
information:

    field   contents                             Fortran format
                                                   for value
    -----   --------                             --------------
     1      RECORD LENGTH IN BYTES                     I8
     2      NUMBER OF HEADER RECORDS                   I8
     3      NUMBER OF SAMPLES PER RECORD               I8
     4      NUMBER OF LINES IN IMAGE                   I8
     5      NUMBER OF BYTES PER SAMPLE                 I8
     6      JPL AIRCRAFT SAR PROCESSOR VERSION         F5.2

     8      RANGE PROJECTION                           A20
     9      RANGE PIXEL SPACING (METERS)               F9.4
    10      AZIMUTH PIXEL SPACING (METERS)             F9.5
    11      BYTE OFFSET OF OLD HEADER                  I8
    12      BYTE OFFSET OF USER HEADER                 I8
    13      BYTE OFFSET OF FIRST DATA RECORD           I8
    14-20   RESERVED FOR LATER USE

Note that character fields are right justified.

    Additional header records contain processing history and other
ancillary information in the same 50-byte field keyword=value format.
