DQ Shift checklist (2020 Apr 7-20)

Task No.	Theme	Substance
1.	Check SummaryPage works or not	See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/monitoring/ Status should be OK
2.	Check Sensitivity & Binary range transition	See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/today/ When you find some transitions, post to klog
3.	Check Spectral line noise (Yesterday)	See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/yesterday/detchar/fscan/ When you find new or disappeared lines, post line information (frequency, transition time, etc.) to klog
4.	Check Lockloss data	See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/today/ We can get the GPS time list at lockloss (GPS end). See below for more challenging characterization.
5.	Check the input power	The EPICS channel showing the input power is K1:LAS-POW_IMC_DC_OUT_DQ
6.	DQ shift Reports	Post the findings on klog, for example, klog12282

Additional DQ challenge: Lockloss investigation

If you have an access to the control room machines, please try to find the cause of lockloss by checking the following important channels! Many of the listed channels can be found in SummaryPages, however it might be difficult to look closer only with it.
Did any suspensions move drastically?
- Check the following oplev channels:
  - K1:VIS-{PRM, PR2, PR3, BS, SR3, SR2, SRM, ITMX, ITMY, ETMX, ETMY}_TM_OPLEV_{PIT, YAW}_DIAG_DQ (urad) for large suspensions.
  - K1:VIS-{MCI, MCO, MCE, IMMT1, IMMT2, OMMT1, OMMT2, OSTM}_TM_OPLEV_{PIT, YAW}_OUT_DQ (not calibrated in urad except MCI, MCE, MCO) for type-C suspensions.
Did any error signals have obvious glitch or saturation?
- Error signal channels are K1:LSC-{DARM, MICH, PRCL, MCL}_IN1_DQ.
Did the OMC DC signal (DARM error signal) have glitches or saturation?
- Check K1:OMC-TRANS_DC_{A,B}_IN1_DQ
Was POP90I buildup (the sideband buildup within the power-recycling cavity, PRC) degrading before lockloss?
- K1:LSC-POP_PDA2_RF90_I_NORM_DQ
Which arm did start degrading first?
- IR X buildup: K1:LSC-TR_X_NORM_OUT_DQ
- IR Y buildup: K1:LSC-TR_Y_NORM_OUT_DQ
- GR X buildup: K1:AOS-TMSX_GR_PDA1_OUT_DQ
- GR Y buildup: K1:AOS-TMSY_GR_PDA1_OUT_DQ
