obspy.core.event.origin.OriginQuality

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

Bases: obspy.core.event.base.__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

pop

If key is not found, d is returned if given, otherwise KeyError is raised.

popitem

as a 2-tuple; but raise KeyError if D is empty.

setdefault

update

If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v

values

Private Methods

Warning

Private methods are mainly for internal/developer use and their API might change without notice.

_pretty_str

Return better readable string representation of AttribDict object.

_repr_pretty_

Special Methods

__bool__

__contains__

__deepcopy__

__delattr__

__delitem__

__dir__

Default dir() implementation.

__eq__

Two instances are considered equal if all attributes and all lists are identical.

__format__

Default object formatter.

__getattr__

Py3k hasattr() expects an AttributeError no KeyError to be raised if the attribute is not found.

__getitem__

__getstate__

__init__

__init_subclass__

This method is called when a class is subclassed.

__iter__

__len__

__ne__

__new__

Create and return a new object.

__nonzero__

__reduce__

Helper for pickle.

__reduce_ex__

Helper for pickle.

__repr__

__setattr__

Custom property implementation that works if the class is inheriting from AttribDict.

__setitem__

__setstate__

__sizeof__

Size of object in memory, in bytes.

__str__

Fairly extensive in an attempt to cover several use cases.

__subclasshook__

Abstract classes can override this to customize issubclass().
