Some (far out) thoughts from NAIF.

Unlikely, but might include request to retrieve associated latest SPICE data.

Might include request to retrieve associated latest SPICE data.

Might want to retrieve data consistent with a particular value or 
range for some geometrical viewing parameter (e.g. L-sub-S, or 
incidence angle), and that parameter, for whatever reason, wasn't 
computed and included in the labels and/or index file when (one of) 
the data set(s) was submitted for archive.

As above, requester might like to limit query based on value or range 
of some geometric parameter that was not included in the labels or 
index file.

Presumably this query would want to use Viking data as well as modern 
data. Presumably easy to find the Viking images, but:

   - may need to convert Viking era LAT/LON to current reference 
frame/coordinate system  (what MIPL is asking NAIF to help provide 
right now)
   - might need some other geometric parameter (e.g lighting angles) 
computed or updated so to be able to fully understand what is being 
seen in the Viking images?

11. Find, retrieve and understand 
characteristics/shortcomings/caveats of latest SPICE data for mission 
X in order to compute some new quantities needed for data analysis or 
correlation.
