Numerous problems with Adobe Connect and phone connections made note-taking
extremely difficult to any level of detail.  In general, reviewers walked
through thier presentations, and some isses identified that were ultimately
PDS3 requriement or limitation were briefly explained but left off the
liens list.  The order of presentations was:

1. Olivier Barnhouin (barnouin.docx)
2. Randy Kirk (kirk.pptx)
3. Bjoern Grieger (grieger.pdf)
4. Nat Bachman (bacham.pdf)
5. Boris Semenov (semenov.pdf)
6. Tony Farnham (farnham.txt)

Other comments were submitted but not discussed by Richard Chen (chen.txt)
and Mike A'Hearn (ahearn.txt).


Critical Liens - must be completed prior to certification:

1. There is an orientation discrepancy between the SPC and MSPCD models that
   needs to be resolved so that both models are consistent with the Cheops
   reference frame.
   
   Discussion points included:
     - There might be several sources of discrepancy, including things
       like pointing improvements in the source data for the different
       models and whether the SPICE data used were in the Cheops frame.
     - Tying either model to the Cheops frame will require some sort of
       reference images in which the Cheops frame orientation can be 
       clearly identified.
       
2. The labels contain placeholder strings in, for example, CITATION_DESC
   that must be removed or replaced with valid information prior to 
   publication and archiving.
   


Additional Liens - must be completed prior to archiving:

In documentation generally -
 1. It appears that "PDS Plate Format" is exactly VRML format.  If this is
    the case, we should NOT be giving a new name to something that already
    has a widely known name. (Note: SBN personnel should probably fix this.)

In "plate_shape_definition.asc" -
 1. Remove the term "planetocentric"
 2. Customize this file with appropriate description for this particular
    shape model collection. (Note: SBN personnel will do this.)
    
In "spc_model_info.asc" -
 1. "with" is misspelled on line 5.
 2. Use the generic term "photoclinometry" rather than "stereophotoclinometry".
 3. Add appropriate subheadings throughout
 4. Add Gaskell, et al. (2008) and Capanna, et al. (2013) to the 
    reference.cat list (which implies they should also be in dataset.cat). 
 5. Add a description of how the models were reduced in resolution to 
    produce the additional versions.
    
In "resolution_images.lbl" -
 1. Add some indication of direction of view (latitude and longitude, e.g.).    
    
In the index directory:

 1. Remove non-data products from the index.tab file.
 
In the dataset.cat file -
 1. Provide a clear description of the role of the PDS archive version 
    number vs. the version number associated with any particular shape
    model (SHAP2 vs V1.0, i.e.). 

In "aareadme.txt" -
 1. Both models are described as being "SPC", but according to other
    documentation it appears that only one actually is.  Correct or 
    clarify, as appropriate.       


Recommendations - implement if possible and reasonable, to aid end users:

In the shape model labels, please add these items:

 1. A list of the source images used in deriving the model. (If the list is 
    long, it can be added as a separate data product, or an additional 
    associated file for model product.)
 2. A derivation/creation date for the model.
 3. Average pixel scales for the input data.
 4. Emission and incidence angles for the input data.
 5. A brief description for the model that includes at least an order of
    magnitude indication of the number of vertices and facers in the
    model table.
 6. Camera parameters
 7. Surface model description
 
 Note also that Nat Bachman's presentation included several suggestions for
 potential improvements in the DSKs.

In the index directory:

 1. Consider adding a science index to tabulate search values for the
    various files included in the data set.
