Notes from PDS NEAR higher level data set review
August 15, 2001.

Introductory stuff.

MSI
===

Started about 9:30am.

Dan Britt leads off with Mathilde 2001 CD.  Impressive.  Hell of a job.
Big change from last year.  Extremely useful, well documented.
He questions the person.cat file.  Do the people really want to be
called about the data, and within a few years the info will be outdated.
Only useful in the short term.  Leave it in.

--> Fix the references to MAG in catinfo.txt.  This applies to all MSI
level 2 CDs.

document directory - Quite impressed with the detail and extent.  Loved
the observation log.  

Nice descriptions of data compression.

index directory - didn't see any problems with it.

mathilde 2002 - actual data.  Likes the thumbnails.  A joy to use.

Dan is quite happy with the Mathilde data set.  Brian asked if anyone looked
at the timing.  He says there was a nine second adjustment during the
Mathilde flyby.  Nobody caught it.  

-->  Add documentation of the nine-second adjustment to the mission catalog
file.  Howard Taylor will do it.

Eros 2001 - Mike Belton asks if the images have been geometry corrected
(for the rectangular pixels).  It has not.  He suggests that maybe the
data should be archived in geometry corrected form.  Brian asks if optical
distortion should also be corrected.  Howard tells about the time line and
how hard it would be to do in the time allowed.  Unreversable correction.

-->  Add a note to the data set cat informing the user that the data have
not been corrected for the rectangular pixels, and telling the geometry
the users need to correct it.

Eros 2218 - Browse directory files have truncated file extensions.

-->  Confirm that the files extensions of the .gif and .lbl files on the
browse directory are correct.

Eros 2325 - No additional problems.

Dave has a complaint about the descriptive material in the data set cat.
He would like it written in a less redundant way.  Simplification of the
data set cat text.  

-->  Simplify the text description in the data set cat to make it less 
redundant.  Dave Tholen will produce a marked-up copy that can be passed
on to Deborah Domingue.

-->  Add an acronym list to the document directory of all data sets.
(Not specific to MSI.  This applies to all instruments.  Start with
the acronym list in the archive plan and update.

That's it for the level 2 MSI.

Fifteen minute break.

Start MSI level 3 at 11am.

Eros 4001 - NASAview cannot look at the .img files in the basemaps directory.
NASAview is not up to date.  Imaging node helped in preparing these files.
Some concern about how accessible these basemap images are, given that
specialized tools are needed to display them.  Dan was not able to view
the files.  Steve Hughes is making NASAview be able to view PC_REAL images
such as these.

-->  Keep the .img's in the basemaps directory and add .tif versions of the
.img images to the extras or browse directory.  Add a note to the aareadme
file to direct users to the .tif  .png, or appropriate lossless format files.
(Lower priority lien, can be dropped if unforseen difficulties arise.)

Dan commends the inclusion of pdf versions of the "grey literature"
tech digest articles in the document directory.  He urges that future
missions should always archive these.  

Dave comments on the data set cat for the shape models.  Is the reference
to the north pole clear?  Call it the angular momentum vector.

-->  Change text in shape model data set cat to clarify the sense of the
rotation in the coordinate system.

All MSI liens go to Howard.  Level three liens also go to Brian Carcich.

160 CDs for level 1b, and 380 CDs for higher-level data, for MSI.
(Approximately.)

Finished at noon.
