Typical event catalogs present information in event based formats because there is a one-to-many relationship between events and observing stations (each event is ‘seen’ by more than one station). This UUEB catalog version is station-based. Each row is an observation from a single station. The following table describes the column entries for each row in the UUEB catalog, which is available in .pkl format within a zip file.
