obspy.core.event.OriginQuality

class OriginQuality(*args, **kwargs)[source]

Bases: obspy.core.event.__OriginQuality

This type contains various attributes commonly used to describe the quality of an origin, e. g., errors, azimuthal coverage, etc. Origin objects have an optional attribute of the type OriginQuality.

Parameters:
  • associated_phase_count (int, optional) Number of associated phases, regardless of their use for origin computation.
  • used_phase_count (int, optional) Number of defining phases, i. e., phase observations that were actually used for computing the origin. Note that there may be more than one defining phase per station.
  • associated_station_count (int, optional) Number of stations at which the event was observed.
  • used_station_count (int, optional) Number of stations from which data was used for origin computation.
  • depth_phase_count (int, optional) Number of depth phases (typically pP, sometimes sP) used in depth computation.
  • standard_error (float, optional) RMS of the travel time residuals of the arrivals used for the origin computation. Unit: s
  • azimuthal_gap (float, optional) Largest azimuthal gap in station distribution as seen from epicenter. For an illustration of azimuthal gap and secondary azimuthal gap (see below), see Fig. 5 of Bond ́ar et al. (2004). Unit: deg
  • secondary_azimuthal_gap (float, optional) Secondary azimuthal gap in station distribution, i. e., the largest azimuthal gap a station closes. Unit: deg
  • ground_truth_level (str, optional) String describing ground-truth level, e. g. GT0, GT5, etc.
  • minimum_distance (float, optional) Epicentral distance of station closest to the epicenter. Unit: deg
  • maximum_distance (float, optional) Epicentral distance of station farthest from the epicenter. Unit: deg
  • median_distance (float, optional) Median epicentral distance of used stations. Unit: deg
