This program requires an observation set of cubes to be initialized with
"spiceinit". It will then apply the offsets in the input jitter table,
after high pass filtering them, to the low pass filtered rotations in the
InstrumentPointing table of the cubes. The low pass filter is achieved by
using a least square solution to compute a polynomial fit of the right
ascension, declination, and twist angles of the rotation. This should reduce
"noisy" pointing data. To restore the original pointing just rerun
"spiceinit".
Note that this program should be used on line scan cameras. It will not work
on framing cameras.
