      The following list documents the contents of the header
information located at the beginning of the EUV and UVS data records.
All values and reference locations are INTEGER*2 (two byte integers)
unless otherwise specified.  (In an EUV file, you may associate to
an Integer*2 to read the header and revert to a byte associate for 
the data.)
      Please contact Karen Simmons if you find errors or have 
questions [(303) 492-8363].
