O3GK reprocess log

This is log of problems and solutions during O3GK reprocess. You can get some plots used in following struggling here

Some channels had error message like Omicron::ExtractTriggers: the maximum trigger rate (5000.00000 Hz) is exceeded 

Case 1: At the lock loss

• ex. K1:CAL-CS_PROC_DARM_DISPLACEMENT_DQ, K1:LSC-MICH_IN1_DQ

  -> Solution: The last 30 sec of segment is not used in Omicron.

Case 2: Appearance or disappearance of line noise

• ex. K1:PEM-MIC_OMC_TABLE_AS_Z_OUT_DQ, K1:PEM-MAG_EXC_BOOTH_EXC_Y_OUT_DQ

  -> Solution: Reprocess Omicron with only failed short segments.

Case 3: Unused channels

• ex. K1:IMC-IMMT1_TRANS_QPDA2_DC_PIT_OUT_DQ, K1:LSC-REFL_PDA2_DC_OUT_DQ

  -> Solution: Skip these channels

Case 4: Strange behavior

• ex. K1:AOS-TMSX(Y)_GR_(Q)PDA1_(SUM_)OUT_DQ, K1:OMC-PZT_LV_OUT_DQ

  -> Solution: Skip these channels (We may better to investigate them )
