Report of the SUP meeting last week---------------------Dan

   The SIRTF observatory is fully integrated.  The instruments are cold.
   The solar panels have been installed.  The end-to-end tests are done.
   The Jan 9, 2003 launch could happen!
   IRAC - No new anomalies.  The PSF is better than expected.
        They will modify the dither tables for a "super-dither".
        They are doing data analysis experiments.  Darks in the 
        lab will be different than darks in orbit.  
   MIPS - SED mode - ready for initial GO call
   IRS - stable - no change in long/low

   Phase B costs - the project has asked for more money from NASA.
   IOC and Science verification plan not that well developed yet.
   They discussed the funding map for this year. For the May Review,
   we should mention the funding shortfalls and delays and quantify
   the impact to GLIMPSE.

New SIRTF Observers Manual

   PSF widths have been updated.  The new version of the SIRTF Observers
   Manual (SOM) has the latest information.  The channels have deeper wells, lower
   bias levels and the saturation limits have been adjusted.
              PSF width
     Band 1     10.5
     Band 2     13.0
     Band 3     14.3
     Band 4     18.6

GLIMPSE Documents

  Science & Data Requirements---------------------John
     Dan is unhappy with the present draft and suggested a new outline.
     John would like to talk about the science of the team to justify
     why we need "x".  Dan would have less discussion of science. Says
     we don't have to resell the science.  Dan will work on a draft.
     Bob likes the tradeoffs table. John and Dan will have frank and 
     useful discussions and converge on a version they both are
     comfortable with.

  Data Products Description----------------------------Barb & Marilyn
     The latest version of the data products document was sent to
     the team for comments.  We will do band-filling for the GPSC
     but not the GBSC.  We are trying to figure out how to
     propagate flags to the mosaic images.  Mark mentions that there
     are errors associated with calculating the zodi that were not
     included in the doc.  There may be a 30% uncertainty in the 
     zodi model for the IRAC bands.  Dan emailed some comments before
     the telecon and Mark also sent comments about the WITS section.

Summer 2003 meeting

     We got cut off at noon (due to the different telecon setup) but
     Ed mentioned in an email later in the day that people should
     think about a GLIMPSE meeting next summer to highlight GLIMPSE 
     science which may be hosted by BU. We'll discuss it in a future telecon.
