Scheduler

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

Bases: object

Schedule a set of ObservingBlock objects

Parameters
constraintssequence of Constraint

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

observerObserver

The observer/site to do the scheduling for.

transitionerTransitioner (required)

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

gap_timeQuantity with time units

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

time_resolutionQuantity 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)[source]

Schedule a set of ObservingBlock objects.

Parameters
blockslist 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.

scheduleSchedule 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
scheduleSchedule

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)[source]

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

Parameters
center_timeTime

Mid-point of time-span to schedule.

durationQuantity or TimeDelta

Duration of time-span to schedule
