O3GK reprocess log

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

6/2: O3GK configuration file is following.

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 )

Some channels had error message like

Sample::SetFrequencies: upsampling is not supported

Omicron::LoadData: incompatible native/working frequency

-> Solution: The channel is moved to appropriate configuration file. (Configuration file is devided by sampling frequency)

Some channels had error message like

Omicron::Condition: input vector is flat

-> Solution: This channel is not working. Skipped.

Some channels had error message like

Spectrum::AddData: the input data vector is too small to compute a PSD with this resolution

Omicron::Condition: warning: this chunk is not used for PSD(1) estimation

-> Because output file is available as usual, this message is ignored.
