Agenda and Minutes, 17 October 2006

Agenda: Tues, 17 October 2006

1) Radiometer status: What should be done about LMXB discussion.

2) Allegro status review:
   - code review: done
   - mathematical review: ?
   - order of magnitude estimates: Warren's still doesn't agree
   - other review committee investigations: Stuart?
   - Allegro-LLO follow-up investigations: Stuart/John/Martin?

3) Start reviewing Allegro-LLO technical documents:

1) Radiometer status: 
   - What should be done about LMXB discussion.
     - OK - more upbeat ending suggested -advanced LIGO and narrow banding.
   - Followup on 3-bin notches
     - Stefan?
   - Other suggestions from Stuart:
     - Should we specify this as a stochastic search?
     - Change 440->400 in eq (17).
     - Second sentence in IV.1.
     - End of section IV, more upbeat as well.
2) Allegro status review:
   - code review: done
   - mathematical review: done
   - order of magnitude estimates: Warren's still doesn't agree
   - book-keeping checks: Robert-John
                          Warren to send robert Allegro SGWB directory.
   - calibration: Harry
   - Allegro-LLO follow-up investigations: Stuart/John/Martin
     - Large-signal bias for hardware injections


3) Start reviewing Allegro-LLO technical documents:
   - Section 2
     - Have Harry Check Allegro Data Analysis cuts 
     - Robert - More and less stringent set of data quality flags
     - Try 30 and 120 second segments
     - What is Allegro data cohering with at 904Hz
       - Look at a couple higher resolutions?
     - 1 bin (1/4 Hz) notching
       - Zoom in graph of 904Hz feature

Hi All,

This is a reminder of action items identified at today's review telecon 
meeting:

1) Warren needs to reconcile his back-of-the-envelope calculation with Martins
2) Robert and John to confirm book-keeping (Warren to provide sgwb directory 
   tarball for Robert).
3) Harry to check Allegro data quality flags as described by Phil Miller in 
   ALLEGRO Data Analysis logbook entry #189 and ALLEGRO Data Analysis logbook 
   entry #190 (there are links in the technical document on page4).
4) Robert to come out with a alternate data quality flag sets that are more 
   and less stringent than those used. Martin/John to rerun with other flags.
5) Martin/John to run with 30/120 second segments.
6) Martin to look at coherence at higher resolution.
7) Zoom in of coherence graph at 904Hz.

We only have two more review meetings before the LSC meeting, so we should try 
to be expeditious.

Thanks,
Warren
