csep.core.catalogs.CSEPCatalog

class csep.core.catalogs.CSEPCatalog(**kwargs)[source]

Standard catalog class for PyCSEP catalog operations.

__init__(**kwargs)[source]
Standard catalog format for CSEP catalogs. Primary event data are stored in structured numpy array. Additional

metadata are available by the event_id in the catalog metadata information.

Parameters:

  • filename – location of catalog

  • catalog (numpy.ndarray or eventlist) – catalog data

  • catalog_id – catalog id number (used for stochastic event set forecasts)

  • format – identification used for serialization

  • name – human readable name of catalog

  • region – spatial and magnitude region

  • compute_stats – whether statistics should be computed for the catalog

  • filters (str or list) – filtering operations to apply to the catalog

  • metadata (dict) – additional information for events

  • date_accessed (str) – time string when catalog was accessed

Methods

__init__(**kwargs)

Standard catalog format for CSEP catalogs. Primary event data are stored in structured numpy array. Additional

apply_mct(m_main, event_epoch[, mc])

Applies time-dependent magnitude of completeness following a mainshock.

b_positive()

Implements the b-positive indicator from Nicholas van der Elst

filter([statements, in_place])

Filters the catalog based on statements.

filter_spatial([region, update_stats, in_place])

Removes events outside of the region.

from_dataframe(df, **kwargs)

Creates catalog from dataframe.

from_dict(adict, **kwargs)

Creates a class from the dictionary representation of the class state.

get_bbox()

Returns bounding box of all events in the catalog

get_bvalue([mag_bins, return_error])

Estimates the b-value of a catalog from Marzocchi and Sandri (2003).

get_depths()

Returns depths of all events in catalog

get_epoch_times()

Returns the datetime of the event as the UTC epoch time (aka unix timestamp)

get_event_ids()

get_latitudes()

Returns latitudes of all events in catalog

get_longitudes()

Returns longitudes of all events in catalog

get_mag_idx()

Return magnitude index from region magnitudes

get_magnitudes()

to_dict()

Serializes class to json dictionary.

update_catalog_stats()

Compute summary statistics of events in catalog

write_ascii(filename[, write_header, ...])
