While developing my Planalyzer program (http://astronomy.mdodd.com/files/Planalyzer.zip), I discovered that Planner's properties don't include the flip margins that ACP uses (flipcnfig.txt) while running a plan. These margins introduce a significant delay in the plan run-time. Does Planner know about these margins and if so, how does it know? More specifically, does Planner include the flip time in its plan duration calculations?

Also, does Planner have any knowledge of when dawn flats must begin? In other words, if I set up a plan where the imaging and darks run until 9:00am and check the Dawn Flats box, will Planner tell me that dawn flats are impossible?

Thanks for any information on these questions.
