Scheduler

class astroplan.Scheduler(constraints, observer, transitioner=None, gap_time=<Quantity 5. min>, time_resolution=<Quantity 20. s>)

Bases: object

Schedule a set of ObservingBlock objects

Parameters:

constraints : sequence of Constraint

The constraints to apply to every observing block. Note that constraints for specific blocks can go on each block individually.

observer : Observer

The observer/site to do the scheduling for.

transitioner : Transitioner (required)

The object to use for computing transition times between blocks. Leaving it as None will cause an error.

gap_time : Quantity with time units

The maximum length of time a transition between ObservingBlocks could take.

time_resolution : Quantity with time units

The smallest factor of time used in scheduling, all Blocks scheduled will have a duration that is a multiple of it.

Methods Summary

__call__(blocks, schedule)	Schedule a set of ObservingBlock objects.
from_timespan(center_time, duration, **kwargs)	Create a new instance of this class given a center time and duration.

Methods Documentation

__call__(blocks, schedule)

Schedule a set of ObservingBlock objects.

Parameters:

blocks : list of ObservingBlock objects

The observing blocks to schedule. Note that the input ObservingBlock objects will not be modified - new ones will be created and returned.

schedule : Schedule object

A schedule that the blocks will be scheduled in. At this time the schedule must be empty, only defined by a start and end time.

Returns:

schedule : Schedule

A schedule objects which consists of Slot objects with and without populated block objects containing either TransitionBlock or ObservingBlock objects with populated start_time and end_time or duration attributes

classmethod from_timespan(center_time, duration, **kwargs)

Create a new instance of this class given a center time and duration.

Parameters:

center_time : Time

Mid-point of time-span to schedule.

duration : Quantity or TimeDelta

Duration of time-span to schedule
