plansinu - Create TFILE for Planetary cubes in Sinusoidal
Create the transformation data file (TFILE) for GEOM (see GEOM for more
information) to project Clementine, Galileo, Mariner, Viking and Voyager
LEVEL 1 cubes to a Sinusoidal Equal-area projection and correct camera
distortions.  This program does not do the actual transformation of the
cube, GEOM must be run using the TFILE created by this program.  If the
map resolution is not input, it is calculated by the program to retain
the full resolution of the LEVEL 1 cube.  The resolution is picked in
increments of 2**n (1. pix/deg, 2., 4. ...) so that any two cubes can
be made the same resolution by doubling or halving one cube.

ADDITIONAL NOTES:

Parm	Description
FROM	Input cube file name. If the file extension is omitted, then ".cub" will be assumed.
TFILE	This is the name given to a data file needed by GEOM. After this program has finished, GEOM must be run to actually transform the cube.
CLON	This is the center longitude of the sinusoidal projection. If CLON is left at the default, the program will set the center longitude of the sinusoidal to be the same as the center longitude of the cube. If you are going to mosaic several cubes while in the sinusoidal projection, you may want to pick a common center longitude for all the cubes in the mosaic. Otherwise, you will have to run NEWMAP which will convert all the cubes to the same center longitude.
KM	Specifies the map resolution in kilometers/pixel. The default will find the map resolution that will retain the full resolution of the input cube.
DEG	Specifies the map resolution in pixels/degree. The default will find the map resolution that will retain the full resolution of the input cube.
LAT	The default procedure is to automatically find the latitude and longitude range of the cube. If you want to enter your own latitude range, the longitude range must be entered also, because if this option is used, the ranges are not determined automatically. WARNING: this option is not very reliable for any cube that includes a limb.
LON	See LAT.
TRIM	If TRIM=YES, the program will create a TFILE that will cause GEOM to project only the area within the longitude boundaries given by the user or determined by the program. If TRIM=NO, no trimming will be done.
