obspy.core.event.origin.Pick

class Pick(force_resource_id=True, *args, **kwargs)[source]

Bases: obspy.core.event.base.__Pick

A pick is the observation of an amplitude anomaly in a seismogram at a specific point in time. It is not necessarily related to a seismic event.

Parameters
  • resource_id (ResourceIdentifier) – Resource identifier of Pick.

  • force_resource_id (bool, optional) – If set to False, the automatic initialization of resource_id attribute in case it is not specified will be skipped.

  • time (UTCDateTime) – Observed onset time of signal (“pick time”).

  • time_errors (QuantityError) – AttribDict containing error quantities.

  • waveform_id (WaveformStreamID) – Identifies the waveform stream.

  • filter_id (ResourceIdentifier, optional) – Identifies the filter or filter setup used for filtering the waveform stream referenced by waveform_id.

  • method_id (ResourceIdentifier, optional) – Identifies the picker that produced the pick. This can be either a detection software program or a person.

  • horizontal_slowness (float, optional) – Observed horizontal slowness of the signal. Most relevant in array measurements. Unit: s·deg^(−1)

  • horizontal_slowness_errors (QuantityError) – AttribDict containing error quantities.

  • backazimuth (float, optional) – Observed backazimuth of the signal. Most relevant in array measurements. Unit: deg

  • backazimuth_errors (QuantityError) – AttribDict containing error quantities.

  • slowness_method_id (ResourceIdentifier, optional) – Identifies the method that was used to determine the slowness.

  • onset (str, optional) – Flag that roughly categorizes the sharpness of the onset. See PickOnset for allowed values.

  • phase_hint (str, optional) – Tentative phase identification as specified by the picker.

  • polarity (str, optional) – Indicates the polarity of first motion, usually from impulsive onsets. See PickPolarity for allowed values.

  • evaluation_mode (str, optional) – Evaluation mode of Pick. See EvaluationMode for allowed values.

  • evaluation_status (str, optional) – Evaluation status of Pick. See EvaluationStatus for allowed values.

  • comments (list of Comment, optional) – Additional comments.

  • creation_info (CreationInfo, optional) – CreationInfo for the Pick object.

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__

reset resource_id’s object_id after deep copy to allow the object specific behavior of get_referred_object

__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().
