Liens resolved Sept 2007, SAM

DIDOC_V3
--------
+ Shortened the original, wide, image parameter tables and moved them
  from the DI flight data sets to this documentation set.  Mike A'Hearn
  issued this lien in April, 2007.

o The organization does not seem to be particularly friendly for general users.
  H. Campins and U. Fink will reply at a later time with suggestions for 
  reorganization.

  + Did not get responses from reviewers about how to re-organize the
    document directory that had about 12 subdirectorie, so I reorganized
    /document into five, very high-level subdirectories which should help
    the general user:
        archive_support
        calibration
        flight_data
        publications
        thermal_vac_data


o The context images (DI HI-IR) for look-back sometimes have the impact site 
  circle in space, rather than on the comet.  This needs correcting - probably
  by removing the circle.

  + Steve Collins, the data provider, had already alluded to this in the 
    "Notes of Caution" section of the lookback_context_images.asc file : 

    4) The estimated impact site as predicted by the ephemeris is marked on
    each context image with a small circle.  It should always be close to the
    impact site on the context-image, but unlike the IR slit positions, any
    ephemeris and sclk-scet errors will effect it to first order.  In other
    words, the position of the IR slit relative to the nucleus
    will be more accurate than the accuracy of the displayed estimated
    impact site.

    I inserted a sentence at the end of this point to reiterate that the
    circle identifying the impact site is usually inaccurate for lookback
    context frames because of spotty ephemeris data.  


o Update Klaasen et al. reference in docinfo.txt.  The years 2006 and 2007 are 
  both listed.

  + Corrected year 2006.


o Add a prominent explanation of what "Earth Received Time" actually is.

  + This applies to the dataset.cat files.  However, the AICDs in this
    document set already describe the "Earth Received Time" keyword found
    in the PDS data labels.


Standards and PDS validation problems:

-volume incomplete - some directories required, on a PDS compliant volume,
 even if empty
        for example, /label/ directory - if no catalog files, at least a
        catinfo.txt file explaining that there are no catalog files

 + Completed the volume:  Added a catalog directory and the most recent 
   DI catalog files along with a catinfo.txt file, added an index 
   directory and indxinfo.txt.


-/root/ directory
 document.html in root directory???  

 + This is for SBN only.  It will not be included in the volume delivered
   to EN.


-/document/ directories
 not all files have an ASCII version.  MS Word and Excel do not
 fulfill this requirement

 + Made ASCII versions of the DI calibration paper, AICDs (that describe
   the data products and archive volumes), and the encounter logs that
   were only in Excel and PDF format.
