Q high-freq minutes Oct 16, 2008 Siong, Brennan, Matt, Jonah (minutes), Michele Siong: I gave update on last review call. Debate on v3 and v4 calibration continues. Brennan: We talked w/ Trento group - concluded that we are not able to validate v3 w/o calibration team contribution. We want to talk to calibration team directly. We have a list of things to do, but they are had to do w/o expert help. Michele: Hopefully they will help us. Matt: I had heard that v4 would be done in a few weeks. Michele: Discussion on Burst group was 4 to 6 months for v4. I don't understand. Brennan: May be a difference between production and validation. Siong: Let's talk about plot scripts. Matt: I looked at plot scripts. Fit is done with script written by Laura, should be ok. Siong: Those should be fine. Matt: Things seem to match up with the plot in the paper - discuss parameter file notes linked from summary table - http://ldas-jobs.ligo.caltech.edu/~jkanner/q-hfs/parameterNotes.txt Jonah: Only unresolved issue is correlation factor https://geco.phys.columbia.edu/omega/wiki/s5y2vsr1/parameters Brennan: We have run over simulations with calibration uncertainty. We could re-run with this turned off if that is better. Siong: We probably do not need to re-run. Jonah: Let's get calibration study linked here. Brennan: Looking at test day, turning this parameter up or down (.1 or 0) does not make a difference. Siong: I'll dig up links with calibration uncertainty checks. -- Discuss DQ flags -- Follow link to Siong's notes: http://www.lsc-group.phys.uwm.edu/bursts/review/projects/s5-qpipe-highf/misc/dq_flag_review.html Siong: Comparesd lists of segments. Things look good. Two questions: 1) Note about applying cuts as part of post-processing seems funny. Brennan: That is a mistake. Some flags applied before processing. 2) The dqdet.script, seems to contain extra flags. Brennan: I this lists all of them. Later, I downselected. Siong: Can I see the ones that were actually used somewhere? Brennan: Yes, it is in the processing scripts. I'll point you to one of those. - Discuss sensitivity estimate - Michele: There is progress. Need to link hrss and corr power gamma. 2 ingredients: 1) probability distribution for gamma. Need probability distribution of the r statistic. So, I did this analysitically by working out relationsihp of r statistic to noise. From that, I get probability distibution of gamma. 2) Plots show relation between hrss and gamma: http://emvogil-3.mit.edu/~bhughey/SG2000Q9gammavshrss.gif http://emvogil-3.mit.edu/~bhughey/SG3067Q9gammavshrss.gif http://emvogil-3.mit.edu/~bhughey/SG5000Q9gammavshrss.gif Brennan: Some of the scatter in plots may be due to antenna patterns. Michele: I think this is moving forward. Now that I have most of this done, I hope to make a document and/or script to compute things. Siong: Looks good. Very promising. Michele: I'll make a web page where I put the scripts, plots, and such. - AOB - Siong: Next week, 10 AM eastern on Tuesday.
