seismic.inventory.dataio.catalogcsv module

Lightweight reader for CSV seismic event catalogs, indexing the found events by event ID and station.

This was adapted for the speical use case of distance-to-event QA checks performed for ticket PST-340.

class seismic.inventory.dataio.catalogcsv.CatalogCSV(event_folder, sampling_factor=1.0)[source]

Bases: object

Lightweight parser for seismic event catalog.

Catalog is format as follows:
