nimsgeoplane - Create NIMS geom. backplanes for all grating positions
"nimsgeoplane" creates backplanes of unprojected NIMS geometry on NIMS
"tubes".  The cube must be an unprojected "tube".  Only one "tube" may
be processed at a time.  "Tubes" may be spliced together with CUBESTACK
or an equivalent program later but caution must be used when splicing
because the STARTING_NATIVE_TIME must be the same for all "tubes" for
some programs.  The NATIVE_TIME backplane must exist for this program
to run.  An auxiliary SPICE file must also exist.  Unless explicitly
named, it is assumed to be in the area associated with the environment
variable $ISISGALDATA and named PLANET_GALILEO_NIMS.gal, where PLANET
is the target body name.  Ex: VENUS_GALILEO_NIMS.gal.

Up to eleven types of geometry backplanes can be created.  The output
options are latitude, longitude, emission angle, incidence angle, phase
angle, the distance from the camera to the point on the surface of the
planet, the local radius or projected radius of the planet, right
ascension angle, declination angle, cone angle and clock angle.  Any
or all of these planes can be selected by entering "YES" for the
corresponding parameter(s).  The backplane data will be 32 bit floating
point format.  An individual backplane for each grating position will
be created.  For example, if latitude and longitude are selected and
there are 12 grating positions, 12 latitude backplanes and 12 longitude
backplanes will be created.

The program will put a set of default mapping parameters in the labels
of the output cube if latitude and longitude backplanes are selected.
The default projection will be Orthographic and the scale will be picked
from the highest resolution recorded during the sequence.  The center
latitude and center longitude are the average subspacecraft latitude and
longitude during the sequence.  The latitude and longitude range are the
actual range covered.

ADDITIONAL NOTES:

ParmDescription
FROM
This is the name of the NIMS "tube" which must have the
native time backplane called NATIVE_TIME.
TO
This is the name of the NIMS "tube" which will contain
selected geometry backplanes.
SFILE
This parameter allows explicit input of the name of an
arbitrary SPICE file in an arbitrary location.  Otherwise,
it is assumed to be in $ISISGALDATA and named
PLANET_GALILEO_NIMS.gal, where PLANET is the target body
name.
DECOFF
This will add a constant offset to the declination stored in
the SPICE file.
RAOFF
This will add a constant offset to the right ascension
stored in the SPICE file.
LAT
When this option is chosen, a backplane is created of the
latitude value at each point.  Latitude will be set to NULL
for any points off the planet.  See RADIUS for exception.
The name of the backplane will be GR_POS_nn_LATITUDE where
nn is the grating position.
LON
When this option is chosen, a backplane is created of the
longitude value at each point.  Longitude will be set to
NULL for any points off the planet.  See RADIUS for
exception.  The name of the backplane will be
GR_POS_nn_LONGITUDE where nn is the grating position.
EMI
When this option is chosen, a backplane is created of the
emission angle value at each point.  Emission angle will be
set to NULL for any points off the planet.  The name of the
backplane will be GR_POS_nn_EMISSION_ANGLE where nn is the
grating position.
INC
When this option is chosen, a backplane is created of the
incidence angle value at each point.  Incidence angle will
be set to NULL for any points off the planet.  The name of
the backplane will be GR_POS_nn_INCIDENCE_ANGLE where nn is
the grating position.
PHASE
When this option is chosen, a backplane is created of the
phase angle value at each point.  Phase angle will be set
to NULL for any points off the planet.  The name of the
backplane will be GR_POS_nn_PHASE_ANGLE where nn is the
grating position.
RANGE
When this option is chosen, a backplane is created of the
distance from the surface of the planet to the camera at
each defined point.  Distance will be set to NULL for any
points off the planet.  The name of the backplane will be
GR_POS_nn_SLANT_DISTANCE where nn is the grating position.
RADIUS
When this option is chosen, a backplane is created of the
local radius of the planet or the projected radius of the
planet (the distance to the closest approach of a vector
that does not intercept the planet) if the NIMS data is not
on the planet.  Also, the latitude and longitude planes
will contain the projected latitude and longitude for
points off the planet.  The name of the backplane will be
GR_POS_nn_RADIUS where nn is the grating position.
RA
When this option is chosen, a backplane is created of the
right ascension value at each point.  The name of the
backplane will be GR_POS_nn_RIGHT_ASCENSION where nn is
the grating position.
DEC
When this option is chosen, a backplane is created of the
declination value at each point.  The name of the backplane
will be GR_POS_nn_DECLINATION where nn is the grating
position.
CONE
When this option is chosen, a backplane is created of the
cone angle value at each point.  The name of the backplane
will be GR_POS_nn_ENCODER_CONE_ANGLE where nn is the
grating position.
CLOCK
When this option is chosen, a backplane is created of the
clock angle value at each point.  The name of the backplane
will be GR_POS_nn_ENCODER_CLOCK_ANGLE where nn is the
grating position.
