Waiting Strategy

In daemon mode the program does the following:

• executes insgen import to generate a new schedule
• Reads the Schedule table (Section ) in database and determines the first request on the list, if there are no requests the wait time is 12 hours
• If the start time is greater than 1 minute away and the slit is open it:
  • If the wait time is less than 60 minutes: executes weatherpause (Section 5.5.5) keeping dome open
  • If the wait time is greater than one hour: executes closedown (Section 5.1.2) shutting observatory down
• sleeps until request is to be observed
• if interrupted: loops
• observes request
• loops

When not in daemon mode it:

• sleeps
• accept reqid= requests
• accept daemon= commands
