Dataset;  All DI datasets

Lien:  The DI pipeline at Cornelll is unable to automatically determine 
the proper geometric information, i.e. choice of target, in many cases.
Thus many of the FITS keywords have 0 entered for pointing information,
and more importantly for range to the target when it is the comet.
Clearly we MUST correct, at least in the PDS labels, as many of these keywords 
as possilbe, certainly including the range to the target in ALL products
where the comet is the target.

Best approach to be determined by figuring out when the automatic routine
fails.  Possibly an interpolation will work, possibly running SPICE software
to calculate the pointing, etc., possibly something else.  This needs science 
input.
