1. S5 First Epoch BNS Inspiral Results Drew Keppel 1 representing the Inspiral Group 1 California Institute of Technology Nov LSC Meeting MIT, 4 November 2006 LIGO-G060556-00-Z

2. Summary Start of run (11/4/05) to start of LHO commissioning (02/06/06) Standard 1 - 3 M  2pN inspiral templates Search pipeline (filter, vetoes, coincidence) Full Data Results »No detection Upper Limit »0.17 L 10 -1 yr -1 for 1.35 M  »Mass dependent Future plans

3. S5 First Epoch BNS Analysis Distance to optimally oriented 1.4,1.4 M  BNS at  = 8 First S5 Epoch Nov 4, 2005 - Feb 6, 2006 current target sensitivity shown in sensemon 2k 4k

4. Parameter Accuracy of recovered software injections Mchirp accuracy: 0.01 M sun End time accuracy: 5 ms

5. Accidental Coincidences and Simulated Signals Tune pipeline using background, playground (10% of data) and injections Measure background by applying time slides before coincidence Add simulated signals to detector data to evaluate analysis performance

6. Vetoes Two types of Vetoes are used to eliminate false triggers »Data Quality Vetoes »Signal-Based Vetoes –  2 waveform consistency test –  2 time above threshold veto All vetoed injections above coincide with glitches. Data Quality Vetoes: categorized »Cat. 1 –Data not analyzed –H1:H2_OUT_OF_LOCK »Cat. 2 & 3 –Triggers discarded –MASTER_OVERFLOW_LSC –PRE_LOCKLOSS_120_SEC

7. H1H2 Amplitude Consistency Effective Distance Cut »For triggers with both H1 and H2 triggers Consistency Cut »For triggers with one Hanford trigger when both were in science mode

8. H1H2 Effective Distance Cut

9. Efficiency Curve 50% efficiency at 25 Mpc

10. Population Model The galaxy catalog has been extended to 100 Mpc »only complete to 25 Mpc »we are now sensitive to those distances »The upper limit has used a catalog extended to 75 Mpc

11. S5 Epoch 1 Full Data Signal with SNR 8 in H1 and L1 detectors would appear here All triggers consistent with background

12. Upper Limit Gaussian Mass Distribution »centered around 1.35 M  »Luminosity for H1H2L1 times:177 L 10 »Upper Limit:0.17 L 10 -1 yr -1 Uniform Mass Distribution »Luminosity for H1H2L1 times: –2-3 M  :155 L 10 –3-4 M  :294 L 10 –4-5 M  :499 L 10 –5-6 M  :1077 L 10 1 MWEG = 1.7 L 10,B »Switched to L 10 ’s because of error in MWEG

13. Mass Dependent Upper Limit Total Mass M  Rate L 10 -1 yr -1 S2 S3/S4 0.19 0.11 0.06 0.03

14. Future for S5 BNS Follow up of loudest events in First Epoch Adding Coherent Code to Pipeline Post-Newtonian search from 2 to ~30 Total M  from 1 calendar year of S5 data »Goal is a result presented at March LSC Meeting 2007
