Environment setting

If you need to install from scratch, https://computing.docs.ligo.org/conda/ will be helpful. Error happens with igwn-py38. ligo-summary-3.7 is OK.

In Kashiwa, m31

Manual script

Script for kashiwa server

https://github.com/gw-detchar/tools/blob/master/Hveto/Script/hveto_O3GK_arg.sh

Usage

> ./hveto_O3GK_arg.sh 2020-04-10 > log.dat 2>&1

Important parameters

SEGMENTFILE : Now it is setting for O3GK. Maybe you need to modify for O4 or later, for example

SEGMENTFILE=/home/detchar/Segments/K1-SCIENCE_MODE/2022/K1-SCIENCE_MODE_UTC_${DIRNAME_DATE}.xml

INIFILE : For O3GK, O3GKC20.ini is used. Detail will be written later again.
OUTPUTDIR : Please set it as you like.
NPROCESS : Originally it was 10 but modified to 1. It is because sometimes multiple process cause error.

ini file

The latest file dedicated for O3GK is O3GKC20.ini. This is based on the ini file used in LIGO, h1l1-hveto-daily-post-o3.ini with some modification for KAGRA.

Important parameters

[segment]
- analysis-flag : You may need to modify it for the online process. The name of the segment list has to be set.
- padding : Please coordinate with the analysis group whether it covers the necessary range.
[primary]
- channel : K1:DAC-STRAIN_C20 is offline data. For online, channel = %(IFO)s:CAL-CS_PROC_DARM_DISPLACEMENT_DQ or channel = %(IFO)s:CAL-CS_PROC_C00_STRAIN_DBL_DQ will do.
- snr-threshold : It maybe better to optimize.
- frequency-range : Please coordinate with the analysis group whether it covers the necessary range.
[auxiliary]
- frequency-range : Please coordinate with the analysis group whether it covers the necessary range.
- channels : Now the channel list is exactly specified here. Before O4, it should be reconsidered. For example, ASC channels may need to be added.
[safety]
- unsafe-channels : Actually this is not necessary if [auxiliary] channels is set, just written to clarify that they must not be used in hveto. Here is the reference of the discussion for O3GK slides.

Note for developper

Maybe it is buggy in the counting of coincidence events ?
Not automated in Kashiwa server.
It will be good if parameter optimization is done with ER data or something.
