>===================================================

>Overall, this appears to be a complete analysis and assessment of the
>Voyager UVS ring occultation data.
>
>At Mark's request, Padma's focus was on the DOCUMENT/SPROFILE files. 
>Padma is unfamiliar with some of the processing steps described here. 
>She has reservations about the way Mark worked backward to retrieve
>the separate star and background count values for the Saturn profile;
>mainly she is unsure whether this is a unique solution or just one of
>many that are equally plausible.

I added further notes in SPROFILE.ASC and SPROFILE.PDF to make it clear
why the calibration reconstruction is unique.

>Most of Padma's UVS data files, including those that she used for her
>thesis, were lost when an old computer was decommissioned. 
>Nevertheless, the optical depth values found on this volume are
>consistent with values she used in her thesis research. Gaps that Mark
>noted in the data files were the result of tape read errors.
>
>Padma referred Mark to a typed memo written by Jude Diner in the early
>1980's that describes the usage of the "E parameter" in detail.  This
>memo also makes the point that occultation error bars are not
>symmetric.  Padma cannot find a hardcopy of this memo but believes
>Phil Nicholson may have a copy somewhere.  Mark will try to find a
>copy.

I checked with Phil but he was unable to find the memo.
