      Since December 2005, the Planning and Scheduling group activates XPS for a continuous 1-min
      integration at filter wheel position 6 (0.1-18 nm range) and only plans a monthly calibration
      experiment.


6. Data Processing Summary

TIM (submitted by Doug Lindholm, 24 July 2008)

             SORCE web site.
         o Normal routine daily processing of version 8 data is ongoing.
   • Work in progress
         o A new text data file format has been finalized. It will be rolled out soon.
         o Planning for version 9.
         o Code modifications (generalizations) to support Glory TIM data processing.
   • Future Plans


SOLSTICE (submitted by Doug Lindholm, 10 July 2008)
  • Status
        o Routine data processing is routinely producing version 9 level 3 FUV and
           MUV SOLSTICE data products. These are available on the SORCE web site
           and LISIRD.
        o MgII index is being produced routinely and is available on the SORCE web
           site.
  • Work in Progress
        o Filter experiment analysis to Improve dead time correction and filter
           transmission.
        o Improvement of alignment analysis from cruciform scans.

                                                                                  Page 6 of 8
