shiftorb - Shift camera angles for an orbit
SHIFTORB uses the MATCH_POINTs between the cubes in the first orbit
(FROM) and the cubes in a control orbit (FROM2) to shift the camera
angles of up to 4096 cubes in the first orbit (FROM).  The error
in the fit between the two orbits is calculated for all the cubes in
the control orbit.  A linear interpolation of the line and sample shift
between two orbits at every degree in latitude is used to correct the
camera angles in the first orbit.  This program is intended to improve
The camera pointing so that automatic control point picking programs
will be able to use a smaller search area for correlation algorithms.
The decision of which orbit is control and which orbit should be shifted
is arbitrary.  For Clementine it would probably be best to choose one
month of orbits as control and shift the orbits in the other month.

ADDITIONAL NOTES:

ParmDescription
FROM
Input cube file names.  If the file extension is omitted,
then ".cub" will be assumed.  This is the entire list of
cubes in the orbit that is to be adjusted.  MATCH_POINTs
must exist between a subset of cubes in this orbit and all
the cubes listed in the control orbit.  Up to 50 cubes can
be listed.
FROMLIST
Due to the limitations of TAE, if more than 50 cubes are to
be adjusted, their names must be put into a file.  A maximum
of 128 characters is allowed for each file name.  List one
file per line.  A maximum of 4096 cubes may be listed.  This
file may contain cubes that will be ignored if the first
column of those cube names contains a !.
FROM2
This is the list of cubes in another orbit which will be
used to determine the amount of shift between orbits.  Do
not list the entire orbit, list only the cubes in this orbit
that have been matched to the first orbit.  There must be
MATCH_POINTs between each cube in this list and a cube in
the first orbit.  A maximum of 50 FROM2 cubes may be listed.
FROM2LIST
Due to the limitations of TAE, if more than 50 cubes are to
be listed, they must be put into a file.  A maximum of 128
characters is allowed for each file name.  List one file per
line.  A maximum of 4096 cube names may be listed.  This
file may contain names that will be ignored if the first
column of those cube names contains a !.
