rand2ck1 - Convert camera angles in Rand format to Naif ckernel
This program reads the camera angles in a Rand formatted ascii table
file and writes them out to a NAIF type-1 (discreet) camera kernel
(c-kernel).
After a c-kernel is created it should be documented by running the
NAIF prorgram commnt. An ASCII comment file will need to be supplied
to the commnt program. For an example of the comments see
/home/dcook/isis/apps/gen/sample_ck_comments.sav
To run commnt type
/usgs/naif/ctools/exe/commnt
and follow the prompts.

ADDITIONAL NOTES:
| Parm | Description |
|---|---|
| MISSION | This is the spacecraft name that will be translated to a NAIF instrument code and used to specify the encoding of the spacecraft clock time. |
| INSTRUM | This parameter is for MISSION=VOYAGER 1 or 2 only. It is ignored for all other missions, but required for Voyager. The program builds Voyager ck files based on actual pointing instances for the instrument instead of the scan platform like other missions so separate ck files are created for each Voyager camera. |
| RANDFROM | This file is a RAND (Mert Davies), ascii geometry table file. Typical extension is rand. |
| SCLKFROM | This file is a NAIF ascii spacecraft clock file. |
| LEAPFILE | This is the NAIF leapseconds kernel file needed to convert the start time in the geometry table to ephemeris seconds past J2000 and finally to the encoded spacecraft clock ticks stored in the output c-kernel. |
| CK1TO | This is the name of the NAIF type-1 camera kernel. It will the contain discreet pointing data from the input file GEMFROM in a single segment. |
| INSTID | This is the NAIF instrument id for the input data.
NAIF supported instrument id's are listed in the
file naif_ids.req.

| REFFRAM | This is the NAIF code for the inertial frame of the data. Typical values are J2000 or B1950. |
| SEGID | This is an identifying string to reference the data. Example: "GLL SCAN PLT -- NAIF -- 18-NOV-90" would identify a ck as Galileo Orbiter scan platform pointing created by NAIF on November 18, 1990. |
| TOL | The search tolerance is used both to screen kernels
as well as to locate pointing data for a specific
instance in time. The beginning and ending times
recorded in the header of the ck created will be
the earliest time less TOL and the latest time
plus TOL for each segment. This padding prevents
times matching the actual first and last entries
from failing the ck screening.
