The 'software/sun' directory contains source code files for simple data

manipulation and access functions for the NIMS Experiment Data Record

(EDR) files contained on this CD-ROM.



NOTE:  For detailed analysis of NIMS data, the EDRs should 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 a description.



There are two programs available in the 'software/sun' directory: 

'addlab.out', and 'edrchk.out'.  A description of each program is provided.



To compile and link the programs on a SUN system, simply execute the

script file 'build.com'



EDRDMP

______



The 'edrdmp' program is not available on the sun system.





EDRCHK

______



'edrchk' provides a means for displaying quality information about a

NIMS EDR, such as percent of valid data, amount of fill data and

telemetry signal-to- noise ratios every minute, and for the whole file,

as well as detailed validity maps at .007 second intervals.  In

addition, 'edrchk' will display various instrument housekeeping and

engineering items every 2/3 second, as well as the PDS label of the

file.



This program may be executed directly from the CD-ROM, or may be copied

to your local disk and executed from there.  Execute the program by 

entering edrchk.out at the system prompt.  You will be asked for the 

following input parameters:



(1)  Enter print option:  1: display header info only

			  2: display header info and grand totals

			  3: display header info, RIM totals

			      every minute) and grand totals

			  4: display everything (data record 

			      info every 2/3 second)



(2)  Enter output list (report) filename, or ^D to exit



(3)  Enter EDR filename (loops on this request, ^D to terminate)



Note: Be sure to wait for system prompts between entering each new

      parameters.





ADDLAB

______



'addlab.out' 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.



'addlab.out' has two command-line arguments - the first parameter must

contain the name of the PDS/EDR labeled file.  Specify the complete

pathname, including the directory specification.  The program will

determine the name of the VICAR label file.  The second parameter is the

output file.



The commands to compile, link and run this program on  SUN UNIX

work station are below.



     SUN/UNIX (build.com command accomplishes this function):

          cc -o addlab.out addlab.c          Will compile and link

                                             the program.

     To execute the program:



          addlab.out edrfile outfile         Will run the program.
