file: dataset.cat
--> Misleading line (minor issue): "This version includes data acquired by the
spacecraft between 08/14/2018 and 01/31/2019. It only includes data downlinked
before 02/01/2019. Future datasets may include mroe data acquired by the
spacecraft after 08/13/2018 but downlinked after 01/31/2019." Suggested change
"This mission phase includes data... This version of the datasets inlcudes only
data downlinked..."

--> There is an added reference to the 0.6 ms exposure time change in ds.cat.
This should be documented somwhere. Why was this done? When was it applied, etc.
Users should not have to wonder if the correction was applied to a particular
dataset or not.

--> DATASET.CAT file states that the dataset used to compute geometry is
NH-J/P/SS-SPICE-6-V1.0. Dataset is available from NAIF, but coverage ends before
this dataset starts (2016) and there isn't a updated set of kernels. Can't check
the geometry in the headers and labels without updated kernels.

DATA
--> Some image headers have a value of -999 for the keyword met_hk. What does
this mean?

--> Error images contain striped flag pattern that may be the result of a
discrepancy between the initally downloaded partial frame and the later
downloaded full frame. Please investigate.
