the laser must not stop operating between warm-up and real science operations.\
During daily communication windows GALA can be switched off. It can be switched off whenever required, but after each power on or after each mode transition back to IDLE, Gala will need a new 90 minutes warm-up phase before starting science.
This observation always nee to be preceded by a GAL_IDLE 'observation'
any rule that is used to schedule the observation: repetition rules, continuous (plasma instruments), one-off, every orbit, every day, etc
