csep.core.forecasts.CatalogForecast

class csep.core.forecasts.CatalogForecast(filename=None, catalogs=None, name=None, filter_spatial=False, filters=None, apply_mct=False, region=None, expected_rates=None, start_time=None, end_time=None, n_cat=None, event=None, loader=None, catalog_type='ascii', catalog_format='native')[source]

Catalog based forecast defined as a family of stochastic event sets.

__init__(filename=None, catalogs=None, name=None, filter_spatial=False, filters=None, apply_mct=False, region=None, expected_rates=None, start_time=None, end_time=None, n_cat=None, event=None, loader=None, catalog_type='ascii', catalog_format='native')[source]

The region information can be provided along side the data, if they are stored in one of the supported file formats. It is assumed that the region for each data is identical. If the regions are not provided with the data files, they must be provided explicitly. The california testing region can be loaded using csep.utils.spatial.california_relm_region().

There are a few different ways this class can be constructed, each

The region is not required to load a forecast or to perform basic operations on a forecast, such as counting events. Any binning of events in space or magnitude will require a spatial region or magnitude bin definitions, respectively.

Parameters
  • filename (str) – Path to the file or directory containing the forecast.

  • catalogs – iterable of csep.core.catalogs.AbstractBaseCatalog

  • filter_spatial (bool) – if true, will filter to area defined in space region

  • apply_mct (bool) – this should be provided if a time-dependent magnitude completeness model should be applied to the forecast

  • filters (iterable) – list of data filter strings. these override the filter_magnitude and filter_time arguments

  • regioncsep.core.spatial.CartesianGrid2D including magnitude bins

  • start_time (datetime.datetime) – start time of the forecast

  • end_time (datetime.datetime) – end time of the forecast

  • name (str) – name of the forecast, will be used for defaults in plotting and other places

  • n_cat (int) – number of catalogs in the forecast

  • event (csep.models.Event) – if the forecast is associated with a particular event

Methods

__init__([filename, catalogs, name, …])

The region information can be provided along side the data, if they are stored in one of the supported file formats.
