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 * * * /home/camera/scripts/ba_on.csh"
  • "15 7 * * * /home/camera/scripts/ba_off.csh"
  • "0 17 * * * /home/camera/scripts/ba_on.csh"
  • "15 17 * * * /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
