Description of the CSV format

The catalog is available for download in CSV format (link below the map on the main page).

The CSV format is more complete than the tabular view shown on the main page.
The main page presents only the mid-percentile Mw values, while the CSV file contains all the computed values, plus the uncertainties.
It is up to the user to decide which values to use.

Event information

• evid: the event ID provided by BCSF-Rénass
• runid: the ID of the SourceSpec run (a new run of the same event is performed, if the event is updated by BCSF-Rénass)
• orig_time: event origin time (UTC)
• lon: event longitude (degrees, east)
• lat: event latitude (degrees, north)
• depth: event depth (km)

Quantities used for computing the source parameters

Please refer to the SourceSpec documentation for more information on how these parameters are used.

• vp: P-wave velocity close to the source (km/s)
• vs: S-wave velocity close to the source (km/s)
• rho: density close to the source (kg/m³)
• kp: "k" parameter to compute the source radius from the P-wave corner frequency (not used, since this catalog is based on S-wave spectra)
• ks: "k" parameter to compute the source radius from the S-wave corner frequency
