Minutes of 2008-July-03 S5 QPipeline Review Teleconference
Shourov Chatterji, Jonah Kanner, Isabel Leonor, Dave Reitze
Minutes by Jonah
Dave: 1) Review status 2) Look at cWB document Dave: On 1), what's been done on Shourov's action items Shourov: Not everything, but have done table based of loudest events. Table is on open box page. Amber Stuver may compare lists of loud events from various pipelines. Shourov: Isabel asked to produce upper limit curves for Q-pipeline only. Laura has made eff. curves - it is a short jump to upper limit curves Shourov: Other action items have not had progress My highest priority is documentation/fixing broken links. Isabel had requested some plots - those are not done yet Need to run on MDC's produced for calibration uncertainty Need to run on irrational time lags Dave: Let's try to prioritize. The goal is to bring the paper to maturity by September. What do you think is most important? I suggested the irrational time lags - that is probably less important Shourov: MDCs are a priority. The thing that needs the most work is the documentation. I think there is a lot lacking in terms of transparency. Dave: Yes, I find being able to go back very useful. Jonah: I'm trying to make a list of checks we've done. I also took a stab at a first principles sensitivity estimate. I multiplyed the noise curve by 7. Shourov: To do the estimate, go to the open box page. Take the thresholds, and convert those to an SNR. At these thresholds, do I get the number of injections I expect. Dave: Shourov, you seemed to get a number that was higher. Where did you get that? Shourov: Go to http://ldas-jobs.ligo.caltech.edu/~shourov/s5y1plots/ You see that the estimates sit ~10x above the noise curve. Dave: Isabel, what are your plans? Isabel: I've already gone through the minutes, and started to summarize what we've looked at. I think we have looked at a lot of the things that we've needed to look at in detail. It would have been good to write the document as we reviewed! Dave: I DO think we've been pretty good at putting in the minutes what we've done. We should be able to look back at those to recall what we did. 2) Dave walks us through cWB document -first part is review process - we can write that I don't think we looked deeply into production of science segments. I think we took it at face value. Jonah: Shourov did check against Laura Shourov: I did check against Laura - the list of DQ and vetoes - is common to all algorithms, so it should likely not be reviewed three times. Maybe we should make a statement that we have NOT done this. Dave: Ok, I think we should touch base with others on this. - continues through cWB document - most of items mentioned we have at least touched on It is not clear that we have to follow this exact format - but it is certainly a good first starting point. Shourov, we've asked you to follow-up on loud events. Dave continues through document. Dave: I think it will be stimulating to take the time and put things in coherently. I think we will want to assign tasks for different sections. Dave: Isabel, you are making a separate code review document Isabel: Yes. Isabel: Who actually types this? Dave: I think, by next week, I will go down the list, and use my judgement to put a list of names by items. Then, circulate and discuss. We should also discuss if we are not clear what goes into document. Shourov: Timescale for burst group as a whole is waiting for a more mature draft. ~ a few weeks Dave: I think we should try to have this done by the middle of August. Isabel: That might work Dave: What about before the L-V meeting? I think that is doable. Shourov: This is not prerequisite for larger review to start Dave: How does this get folded into review? Isabel: I think the main review is more for the paper. Shourov: Also, DQ, segments, combining results, etc... Dave: For next week, I'll asign tasks and comment on template. Dave: What are the prospects for improving the documentation in the next week or 2. Shourov: Yes I can. Dave: Let's meet at the same time next week. Jonah: Let's try to make a table of things we've checked. Dave: Great. I think we have a clear picture of next steps.
* Shourov works on improved documentation * Dave assigns tasks/comments on template * Jonah works on list of completed tasks
