After that, we need volunteers to test the DetChar tools on new conda environment. * what is the time line? * Installation will finished before the end of March. From April, the test will start. Volunteers are helpful. * DQ flags for O4 * In last PEM meeting, Yuzurihara presented the current status and received the helpful comments. [slide](https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=13970) * We will change our plan to construct the data quality flag and will compute the BLRMS of gwpy to set the threshold. * The review is necessary before O4. (probably very close to O4, because we need ER) * DQR update * no update * Commissioning of GreenX * In the last weekend, the commissioner tried continuous GreenX. During that trials, they found many short term lock loss (~10 ms). 10 ms is too short to follow the suspension motion, so it is likely that there are some causes of the lock loss except for the suspension motion. * The commissioner needs helps DetChar members to identify the cause or give a hint of the cause. * For details, see [[https://klog.icrr.u-tokyo.ac.jp/osl/index.php?r=19963|klog#19963]] [[https://klog.icrr.u-tokyo.ac.jp/osl/index.php?r=19983|klog#19983]] * main channel K1:TMS-X_GR_PDA1_OUT_DQ * time : 2022 Mar 06 23:37:50 UTC = 2022 Mar 07 8:37:50 JST = GPS time 1330645088 |
