Subject:        Data Monitoring Tools in LSC data anlayses?

As we get the DASWG moving forward on outstanding software issues,
I would like the four of you to produce a brief (2-page) report on
each of DMT and GEO++ as a tool for large scale analysis of LSC data.
In preparing the report,  I would ask that you consider the following
issues:

        1)  Accessibility/cost of DMT/GEO++ to entire collaboration.
        
        2)  Platform and other support of DMT/GEO++.
        
        3)  Possibility to hook libraries (e.g. LAL, etc) into
        DMT/GEO++ to leverage other existing code bases.
        
        4)  How version control,  documentation and validation should
        be handled.

I expect that DMT/GEO++ will remain as detector characterization tools
producing results which feed into analyses in the form of vetoes, data
quality cuts,  and other astrophysically uninterpreted ways.

Your report will be brought to the DASWG for discussion.  After the
broader discussion,  we will bring a recommendation to the executive
committee for adoption at the March LSC meeting.   

Whatever the outcome of discussions within the DASWG,  I plan to
reconsider all questions relating to software starting in early 2005
when I hope we can start strategic planning for Advanced LIGO data
analysis.

Thanks,
Patrick
