observability_table¶
-
astroplan.observability_table(constraints, observer, targets, times=None, time_range=None, time_grid_resolution=<Quantity 0.5 h>)[source]¶ Creates a table with information about observability for all the
targetsover the requestedtime_range, given the constraints inconstraints_listforobserver.Parameters: constraints : list or
ConstraintObservational constraint(s)
observer :
ObserverThe observer who has constraints
constraintstargets : {list,
SkyCoord,FixedTarget}Target or list of targets
times :
Time(optional)Array of times on which to test the constraint
time_range :
Time(optional)Lower and upper bounds on time sequence, with spacing
time_resolution. This will be passed as the first argument intotime_grid_from_range.time_grid_resolution :
Quantity(optional)If
time_rangeis specified, determine whether constraints are met between test times intime_rangeby checking constraint at linearly-spaced times separated bytime_resolution. Default is 0.5 hours.Returns: observability_table :
TableA Table containing the observability information for each of the
targets. The table contains four columns with information about the target and it’s observability:'target name','ever observable','always observable', and'fraction of time observable'. It also contains metadata entries'times'(with an array of all the times),'observer'(theObserverobject), and'constraints'(containing the suppliedconstraints).
