obspy.io.gse2.bulletin._read_gse2

_read_gse2(filename, inventory=None, default_network_code='XX', default_location_code=None, default_channel_code=None, res_id_prefix='smi:local', fields=None, event_point_separator=False, agency=None)[source]

Read a GSE2.0 bulletin file and returns an ObsPy Catalog object.

Warning

This function should NOT be called directly, it registers via the ObsPy read_events() function, call this instead.

Parameters:

filename (str) – File or file-like object in text mode.
inventory (Inventory) – Inventory used to retrieve network code, location code and channel code of stations.
default_network_code (str) – Default network code used if stations are not found in the inventory.
default_location_code (str) – Location code used if stations are not found in the inventory.
default_channel_code (str) – Default channel code used if stations are not found in the inventory.
res_id_prefix (str) – Prefix used in ResourceIdentifier attributes.
fields (dict) – dictionary of positions of input fields, used if input file is non-standard
event_point_separator (bool) – True if events are separated by point rather than 2 empty lines.
agency (str) – Agency that generated the file.

Return type:

Catalog

Returns:

An ObsPy Catalog object.
