1. CW Search GroupStatus Summary: August 2005M.Alessandra Papafor the CW group G05yyxx-00-Z

2. 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. • Einstein @ 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)

3. 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 2006. - 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.

4. S5 Plans • Searches that can be “fast-tracked” , but notonline • 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. E @ h

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