AlertFollowup

Note

Class for followup to Alert events, using a spatial prior and a fixed spectral index of 2.5 in the likelihood.

General Alert followup class

class fast_response.AlertFollowup.AlertFollowup(name, skymap_path, tstart, tstop, skipped=None, seed=None, outdir=None, save=True, extension=None)

Class for external skymap followup. By default, uses a fixed index of 2.5 in LLH. Built on the PriorFollowup class

generate_report()

Generates report using ReportGenerator.AlertReport attributes and the ReportGenerator Class

ps_sens_range()

Compute the minimum and maximum sensitivities within the 90% contour of the skymap

Returns:

lowest sensitivity within the 90% contour of the skymap highest sensitivity within the 90% contour of the skymap

Return type:

float, float

run_background_trials(ntrials=1000)

For alert events with specific time windows, just use precomputed background arrays

Returns:

tsd – test-statistic distribution with weighting from alert event spatial prior

Return type:

array-like

sens_range_plot()

For alert events, make a sensitivity plot highlighting the region where the contour lives

upper_limit()

Sensitivity Range (not truly an UL) for the full declination range of the map. Also makes a plot of the sensitivity range versus dec, with relevant decs highlighted

write_circular(alert_results)

Generate a circular from internal followup template. Saves a text file in the output directory as alertid_circular.txt

Parameters:

alert_results (dict) – Dictionary of results from the two time window analyses

Track Followups (Gold and Bronze)

class fast_response.AlertFollowup.TrackFollowup(name, skymap_path, tstart, tstop, skipped=None, seed=None, outdir=None, save=True, extension=None)

Class for followup of track alert events By default, uses a fixed index of 2.5 in LLH. Assumes a probability skymap for the follow-up. Built on AlertFollowup and PriorFollowup base classes

Cascade Followups

class fast_response.AlertFollowup.CascadeFollowup(name, skymap_path, tstart, tstop, skipped=None, seed=None, outdir=None, save=True, extension=None)

Class for followup of cascade alert events By default, uses a fixed index of 2.5 in LLH. Built on the AlertFollowup and PriorFollowup base classes
