# Transitioner¶

class astroplan.Transitioner(slew_rate=None, instrument_reconfig_times=None)[source]

Bases: object

A class that defines how to compute transition times from one block to another.

Parameters: slew_rate : Quantity with angle/time units The slew rate of the telescope instrument_reconfig_times : dict of dicts or None If not None, gives a mapping from property names to another dictionary. The second dictionary maps 2-tuples of states to the time it takes to transition between those states (as an Quantity), can also take a ‘default’ key mapped to a default transition time.

Methods Summary

 __call__(oldblock, newblock, start_time, ...) Determines the amount of time needed to transition from one observing block to another. compute_instrument_transitions(oldblock, ...)

Methods Documentation

__call__(oldblock, newblock, start_time, observer)[source]

Determines the amount of time needed to transition from one observing block to another. This uses the parameters defined in self.instrument_reconfig_times.

Parameters: oldblock : ObservingBlock or None The initial configuration/target newblock : ObservingBlock or None The new configuration/target to transition to start_time : Time The time the transition should start observer : astroplan.Observer The observer at the time transition : TransitionBlock or None A transition to get from oldblock to newblock or None if no transition is necessary
