On last Sunday, the ETMX camera was restarted and its exposure was changed from 500 to 10000 by the ini file, which caused the camera servo issue. To avoid this, we changed the ETMX/ETMY camera exposure in the ini files. The BS camera exposure in the ini file is good for camera servo.

The ini files for ETMX/ETMY/BS camera are stored in following place.

ETMX: /opt/rtcds/ifo/lho-pylon-camera-config/H1-VID-CAM-ETMX.ini
ETMY: /ligo/cds/lho/h1/camera/H1-VID-CAM27.ini
BS: /ligo/cds/lho/h1/camera/H1-VID-CAM26.ini

The camera exposure we set in the ini file is as follows. The original exposure in the ini file was 10000.

ETMX: 500
ETMY: 3500
BS: 10000

To load the updated ini file, the camera needs to be restarted. We should restart ETMX/ETMY camera when the camera servo is OFF.
