class nu_coincidence.coincidence.CoincidenceCheck

Bases: object

Abstract base class for coincidence checks.

check_spatial()

check_temporal()

nu_coincidence.coincidence.check_spatial_coincidence(event_ras, event_decs, event_ang_errs, event_src_labels, population_ras, population_decs)

Check the spatial coincidence of events assuming circular error regions with the sources in population, which are assumed to be points.

All angles should be in radians.

nu_coincidence.coincidence.check_temporal_coincidence(event_times, event_src_labels, event_ras, event_decs, event_ang_errs, spatial_match_inds, population_variability, population_flare_times, population_flare_durations, population_flare_amplitudes)

Check the temporal coincidence of events, both in the sense of variable objects and actual flares. Also requires a spatial match

nu_coincidence.coincidence.count_spatial_coincidence(event_ras, event_decs, event_ang_errs, population_ras, population_decs)

Count the spatial coincidence of events assuming circular error regions with the sources in population, which are assumed to be points.

All angles should be in radians.

nu_coincidence.coincidence.get_central_angle(ref_ra, ref_dec, ras, decs)

Get the central angles between ref_ra and ref_dec and a bunch of ras and decs. Angles should be in radians.

Useful for computing the separation of points on the unit sphere.
