Operation test to generate segment files by new script

On k1det1 (in `igwn-py38` environment), I started the operation test to generate segment file by new script reported at klog#24272.

The generated segment files are stored at `/users/DET/tools/Segments/Script/tmp/`.

I compared the result of the generated segment files (both text files and xml files) since March 13. The script to compare old and new segment is put at `/users/yuzu/script/segment/compare_segments.sh`

What I found

  • For segment of `K1:GRD-PEM_EARTHQUAKE_STATE_N == 1000`
    • No difference in xml file, except for the treatment of time of missing frame files.
      • The old script can't handle the missing frame files, such as on the maintanance day.
      • The new script (developed by Uchikata-san) can treat the missing frame files and exclude the missing time from the length of segment_definer in xml files.
    • No difference in text file.
    • Sometimes, there is 1-second difference between old and new segments, because of the different direction to round the value (round down / round up). We should add the option to select the round way, based on the user's requirement. This is a remained task.
  • For segment of `K1:FEC-32_ADC_OVERFLOW_0_0 != 0`
    • No difference in xml file, except for the treatment of time of missing frame files.
    • No difference in text file.
  • For segment of `K1:FEC-32_ADC_OVERFLOW_0_0 == 0`
    • No difference in xml file, except for the treatment of time of missing frame files.
    • No difference in text file.
  • For segment of `K1:GRD-LSC_LOCK_STATE_N == 10000`
    • No difference in xml file, except for the treatment of time of missing frame files.
      • The remained task is to do the operation test of Omicron and Hveto by using the new xml file.
    • No difference in text file.
  • For segment of `K1:GRD-LSC_LOCK_STATE_N != 10000`
    • No difference in xml file, except for the treatment of time of missing frame files.
    • No difference in text file.
  • For segment of `GRD-IFO_STATE_N == 1000`
    • No difference in xml file, except for the treatment of time of missing frame files.
    • No difference in text file.
    • Now, we can't test this segment, because we don't have a data of science mode. 

Note

  • The generated segment is designed to be shorter than actual values. This is bacause in the analysis, we will take the margin around the both edge of begining and end time. So, we round up the start time and round down the end time, to be interger values.
  • But, in the GRD-PEM_EARTHQUAKE, the idea of the implemention is opposit to other flags. When no earthquake, the guardian value will be 1000. We should add the option to select the round way, based on the user's requirement.

Relationship with Omicron

  • I checked the script to run the Omicron regularly at Kamioka : `/users/DET/tools/Omicron/Script/automation_segment.sh` The script checks the locked segment (segment="/users/DET/tools/Segments/Script/Partial/K1-GRD_LOCKED_SEGMENT_UTC_"$date".txt"). Because there is no difference in text file of both old and new locked segments, no affect on running Omicron.
