NOTE:  Most scientific analysis of NIMS data should be done on spectral
image cubes.  Versions of these cubes generated by the NIMS team are
available in another CD-ROM series.  If these are inadequate, the EDRs
may be processed into spectral image cubes.  This can be done with cube
generation software available in either the ISIS or Vicar processing
systems, which must be obtained independently.  See VOLINFO.TXT for details.

Source code for software which performs simple data manipulation and access
functions for the NIMS Phase 2 Experiment Data Record (EDR) files contained
on this CD-ROM is available at the NIMS web site:

	http://jumpy.igpp.ucla.edu/~nims.

The two programs are EDRDMP2 and ADDLAB.  There is also a CDCOPY command
file to be used on older VAX/VMS systems for copying data files from
CDROM media.  A brief description of each program and the command file
follows.  Detailed instructions on their use accompany the source files.

EDRDMP2
_______

EDRDMP2 is a Fortran program which displays data values from a NIMS EDR
in a selected spacecraft clock range.  Its use does, however, requires
some familiarity with the design of the NIMS instrument and the order
in which NIMS data is transmitted from the spacecraft.  As noted above,
science analysis should normally be done from NIMS cubes which may be
acquired separately or generated from the EDRs.

To use EDRDMP2, you must understand the way the NIMS EDR is organized
in spacecraft clock time, and the way the NIMS instrument data is
structured by detector, grating position and secondary mirror position.
For this information, see the file NIMSINST.TXT and chapters 3 and 4 of
VOLINFO.TXT.

ADDLAB
______

ADDLAB is a C program which combines the VICAR label found in the
VIC subdirectories and the PDS-labelled data files found in the EDR
subdirectories. The program is used solely to create a file for the
VICAR NIMS cube generation software, which requires VICAR-labelled EDRs.

CDCOPY.COM
__________

The CDCOPY command file may be used on older VAX/VMS systems for
copying data files from CDROM media to VMS magnetic disk media.
This command file is used in conjunction with the VFS-ISO 9660
MOUNT field test kit which allows VMS interface with the CDROM
ISO volume and directory standard.  CDCOPY is no longer needed
on systems running VMS version 6.0 or later versions.
