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:

ParmDescription
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.

        Lunar Orbiter 5    all            -535000
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.
