\f0\fs24 \cf0 Liens on the 1997 PDSSBN Asteroid Data Sets.\
March 26, 1997.\
\
***Liens which are explicitly assigned to an individual are starred. All\
others will be Carol's responsibility either to resolve them or see to it\
that they get resolved. Please scan for stars and note your own action items.\
\
I. Proper Elements.\
\
1. In the description of each label, give the number of asteroids included \
in the data table.\
\
2. In the catalog description, give a table of all the data tables telling\
how many asteroids are included in each, and the total number of asteroids \
in the data set.\
\
3. In the catalog, give a one-paragraph "primer" to proper elements, with \
a pointer to Milani's paper for more details.\
\
4. REFERENCE_KEY_ID values are restricted to 20 characters, but one \
exists in propel.cat longer than this. Shorten it.\
\
II. Shape Models\
\
1. Define the pole of the coordinate system for each shape model.\
\
2. Tell how latitude and longitude are defined.\
\
3. In the label description, give a brief explanation of mapping \
conventions as they apply to these shape models.\
\
4. Restore the missing s0 at the beginning of the Galileo clock numbers or\
determine why it is missing.\
\
5. Restore line and sample to their usual order in the image list.\
\
6. Clarify the explanation of how the low resolution areas are "oversampled".\
\
***7.  Use keywords to capture the coordinate system of the image mosaic\
in the image labels. Anne will find out about existing keywords to do\
this.\
\
8. If possible, include more information in the FITS headers.\
\
9. Include a statement of the highest resolution in each image in the\
image label.\
\
10. If possible, get a table of images used in the image mosaics for all\
bodies, similar to that provided for Ida and Gaspra.\
\
11.  Ask Thomas if he has generated uncertainties for the shape model values,\
and if so, get them.\
\
12. Fix typo in catalog: S11 Epimetheus is referred  to as S11 Hyperion.\
\
III. Dynamical Families:\
\
1. Only the full file will be ingested as a PDS data set. The individual families \
files will be offered as a service until the relational database}
