list_kernels_for_day() returns old UVIS instrument kernel. #29

Open spacemanjosh opened 2 years ago

spacemanjosh commented 2 years ago

Currently, the subset tool from the NAIF website points at an older copy of the Cassini UVIS kernels. The discrepancy comes from the difference in kernels located in this kernel release: https://naif.jpl.nasa.gov/pub/naif/pds/data/co-s_j_e_v-spice-6-v1.0/cosp_1000/data/ vs. the kernels found here: https://naif.jpl.nasa.gov/pub/naif/CASSINI/kernels/

This can be reproduced by utilizing the list_kernels_for_day() function: kernels = list_kernels_for_day('cassini', '2014-265', '2014-265') and then comparing the returned list of kernels to the kernels found at the second link above.

Specifically, the following two kernels seem to be out of date: cas_uvis_v06.ti cas_v41.tf

But the most current versions of these are: cas_uvis_v07.ti cas_v43.tf

This of course is dependent on the subset service provided by NAIF, so a workaround would have to be implemented in the short term until NAIF updates their tool.
