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 targets over the requested time_range, given the constraints in constraints_list for observer.


constraints : list or Constraint

Observational constraint(s)

observer : Observer

The observer who has constraints constraints

targets : {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 into time_grid_from_range.

time_grid_resolution : Quantity (optional)

If time_range is specified, determine whether constraints are met between test times in time_range by checking constraint at linearly-spaced times separated by time_resolution. Default is 0.5 hours.


observability_table : Table

A 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' (the Observer object), and 'constraints' (containing the supplied constraints).
