C_DESCR Structure of NIMS EDR file header records:  See NIMS EDR SIS.

C	Total length 2048 bytes (2 records).

C

C	Note that the RIM count is in the high-order 3 bytes of the

C	spacecraft clock item.  For ease of use, it should probably

C	be extracted into the 3 low-order bytes of a 4-byte longword,

C	with zero high-order byte.  Likewise, the minor frame count

C	byte can be inserted into its own 4-byte item.



C_LIMS  MISC array to be replaced by detailed spec of 29 EDR items
