To (re)start the regular twice a day operation of the high-vacuum BA gauge, or to turn off that automatic operation, the crontab on yggdrasil must be edited
To edit the crontab:
- log into yggdrasil as camera
- issue a "crontab -e" (for edit) command
- If the necessary lines are comment out, remove the comments
- If the lines are absent, then add them:
- "0 7 * * 1 /home/camera/scripts/ba_on.csh"
- "15 7 * * 1 /home/camera/scripts/ba_off.csh"
- "0 17 * * 1 /home/camera/scripts/ba_on.csh"
- "15 17 * * 1 /home/camera/scripts/ba_off.csh"
- To turn off the BA gauge action, either delete or (better) comment out the lines
- be sure to comment out all four lines, not just a single line
