New Horizon MVIC Specific Liens for Pluto Encounter Data Sets
-------------------------------------------------------------

Certification Status: Certified; post with liens and notes.


Need to provide coefficients/guidance/suggestions on how to calibrate small moons, etc. 

Add the calibration coefficents to the PDS labels.  The FITS headers contain the coefficents, but they are string format.  It would be easier if they were floating point (eliminates a step).

Add geometric information in the FITS headers to the PDS labels.  It would be useful to add pointing to the label as well.

My calculations suggest there is a mix of positions calculated with and without light time corrections.  For geometry listed in PDS labels (defined as light time corrected):
--> s/c – target position is best matched with "lt+s"
--> s/c – Sun position is best matched with no correction  (incorrect)
--> Target – Sun position best matched with "lt+s"
--> s/c – Earth  position best matched with "lt+s
For FITS headers, 
--> target-s/c  is given as the inverse of s/c-target (incorrect)
--> Earth – s/c  is given as the inverse of s/c-target (incorrect)

Phase angle in the PDS labels appears to be incorrect as with LORRI.

Include exposure time and additional information, such as more geometry information, calibration constants used, etc.,  in PDS labels 

Long documentation in PDS label file for the FITS extension WINDOW_MISMATCHES table for windowed observations, but need a pointer somewhere in dataset level documents to tell users the location of this description


For file: 'calib/calinfo.txt'
--> typo: "Supreceded"  should be "Superceded"   or "Superseded"

For file: 'catalog/dataset.cat'
--> For the statement: "some sequences may have failed to execute due to spacecraft events (e.g. safing) and there will be observations associated with those sequences."
--> --> Is this correct?
--> --> Not clear if observations are not obtained, or if they are obtained with bad pointing, etc. 
--> --> More detail would be useful.
--> Is it straightforward to determine what sequences were not obtained, simply by comparing to the index table.
--> Is it possible to get a list of known "interruptions" that might have affected the data sequences, just as a basic guide (e.g. a table of times when observations might have been affected)?
--> The following paragraph in the calibrated data set is confusing: "A PDS OBJECT CALGEOM (FITS extension) with a correction for geometric distortion, present in previous versions of MVIC data sets, has been removed from these and future PDS calibrated data sets.  Geometric distorion will be addressed in higher-level products, as it involves resampling the data."
--> --> also minor typo: distorion => distortion

For file: 'data/*/*.lbl'
--> DETECTOR_ID = "NIR" or "BLUE" or ... That keyword should be used in conjunction with DETECTOR_DESC, which describes the detector.

For file: 'document/ralph_ssr.pdf'
--> The Ralph instrument SSR paper (Reuter et al.) described in aareadme.txt may be outdated. Perhaps use a more recent version; e.g., https://arxiv.org/ftp/arxiv/papers/0709/0709.4281.pdf

For file: 'NOTES/introdoc.pdf'
--> In the finding the data paragraph, the filename definition includes a version number after the "eng" or "sci" identifier, but none of the files contains this version number and it is not mentioned in any other documentation.
