Follow-up observations After image analysis, all EM telescopes did not find any transient events in their images. 15

Significance of the event L 1 -H 1 -V 1 network SNR of L 1: 9. 2, H 1: 13. 8, V 1: 4. 9 network correlation: 7. 4, rho: 4. 1 IFAR: 3. 27 years ( < 8 years, our threshold) No detection from burst search 13. 1 years, 200 non-zero lags 24. 9 days, zero lag 4. 1 0. 74 16

CBC search False alarm rate is 1/7000 years, significant enough! 17

Blind injection (pulsar type) S 6 dの解析が終わる前にオープンにされてしまった。 20日のようなshort-lived 信号はobservation intervalを変えずに現パイプラインを走らせても検出できない。 Narrow band searchでfollow-upしたら検出できた。 Estimated SNRs are: H 1 47, L 1 39, V 1 17 28
