I see SPICE kernels in two different places:

https://naif.jpl.nasa.gov/pub/naif/CASSINI/kernels/
https://naif.jpl.nasa.gov/pub/naif/pds/data...cosp_1000/data/

They don't match up, does anyone know which would be the recommended set to look at?

Many thanks

Thought I'd try out the moon images to set the filter balances. I tried a difference image between LUNAR_SCIENCE (CL1,UV3) and 0.8*(CL1,IR1) and get the attached, the white spots are interesting and show more detail than just the brightness.

A linear scaling doesn't get a flat difference over the moon surface and adding an offset just falls out into a constant, I'm guessing there's some non-linearity I'm missing...
