Transitioner

class astroplan.Transitioner(slew_rate=None, instrument_reconfig_times=None)

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.

Methods Documentation

__call__(oldblock, newblock, start_time, observer)

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

Returns:

transition : TransitionBlock or None

A transition to get from oldblock to newblock or None if no transition is necessary
