CW Search Group Status Summary: August 2005 M.Alessandra Papa for the CW group G05yyxx-00-Z

Major Search Efforts Currently Underway -Hough Search - S2 data paper (CW paper III) - Primary points of contact: A. Sintes, B. Krishnan - Status of Expected Publications: today asking for approval for gr-qc posting. -Fstat Search - S2 data, all-sky search for isolated pulsars, search for signal from Sco- X1 (pulsar in a binary system) (CW paper IV) - Primary points of contact: A. Vecchio, M.A. Papa -Status of Expected Publications: results have not changed for months. Undergoing further pipeline studies and checks, and revision in the presentation of results. Expected submission to gr-qc in Fall. home - S3 data: analysis complete, reviewing results. S4 analysis underway. Will continue until end of the year. - Primary point of contact: B. Allen - Status of expected Publications: today asking for approval for web illustration of a small fraction of S3 results. - Will write an S5 paper (CW paper VII)

Major Search Efforts Currently Underway - Powerflux Search DC work - S4 data, all-sky, wide band search for isolated pulsars (CW paper V) - Primary points of contact: K. Riles, V. Dergachev -Status of Expected Publication: code review is complete, results are being produced now and will be presented in Nov. A draft to the LSC is expected in early Stack-slide Search - S4 data, all-sky, wide band search for isolated pulsars (CW paper V) - Primary points of contact: G. Mendell - Status of Expected Publication: code review under way (high priority), preliminary results are expected for Nov. Working hard to make it in paper V. - Hough Search - Making improvements to S2 pipeline and if completed in time, will be included in the CW paper V. - Time-domain - S3-S4 data, total of 93 (33 isolated, 60 binaries) known pulsars, including GEO data when relevant (CW paper VI). S3 results review nearly complete. - Primary points of contact: M. Pitkin, G. Woan - Status of expected Publication: submission to gr-qc for early 2006.

S5 Plans Searches that can be “fast-tracked”, but not online »Time-domain searches for known objects –Results updated every, say, month »Incoherent methods –Blind all-sky,wide-band searches. Monthly results. –Might be reasonable to release results every 6 months. –Computational cost: it increases with time. For 4 months of data, no spindown, all- sky, 1500Hz band, 2 IFOs: with 400CPUs (nearly dedicated) we need 2 weeks. If the band goes up to only 700Hz then we only need a couple days. General outline of S5 plans »Fast-tracked: both the time-domain searches and the incoherent searches will analyze increasingly large chunks of data, as described above. »Online daily fast scan of data without Doppler modulation correction. Computational cost negligible. »Online SFT-production –Under Onassys –group will transition to SFT.v2 –Uncalibrated and different flavours of calibrated SFTs will be produced – Negligible computational cost (work on 1 node sporadically) »Goal: deepest, blind, wide-band search : hierarchical also w. h

Key Questions that need to be addressed by collaboration Approval of S2 Hough paper Approval of representative S3 h web pages Other issues »Cluster time for DC work and for fast-tracked searches during S5 »SFT production needs to happen
