obspy.core.event.source.Axis

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

Bases: obspy.core.event.base._event_type_class_factory.<locals>.AbstractEventType

This class describes an eigenvector of a moment tensor expressed in its principal-axes system. It uses the angles azimuth, plunge, and the eigenvalue length.

Parameters
  • azimuth (float) – Azimuth of eigenvector of moment tensor expressed in principal-axes system. Measured clockwise from South-North direction at epicenter. Unit: deg

  • azimuth_errors (QuantityError) – AttribDict containing error quantities.

  • plunge (float) – Plunge of eigenvector of moment tensor expressed in principal-axes system. Measured against downward vertical direction at epicenter. Unit: deg

  • plunge_errors (QuantityError) – AttribDict containing error quantities.

  • length (float) – Eigenvalue of moment tensor expressed in principal-axes system. Unit: Nm

  • length_errors (QuantityError) – AttribDict containing error quantities.

Note

Private Methods

Warning

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

Axis._cast_type(key, value)

Cast type of value to type required in _types dict.

Parameters
  • key (str) – The key from __setattr__.

  • value – The value being set to key.

Returns

value cast to correct type.

Axis._pretty_str(priorized_keys=[], min_label_length=16)

Return better readable string representation of AttribDict object.

Parameters
  • priorized_keys (list[str], optional) – Keywords of current AttribDict which will be shown before all other keywords. Those keywords must exists otherwise an exception will be raised. Defaults to empty list.

  • min_label_length (int, optional) – Minimum label length for keywords. Defaults to 16.

Returns

String representation of current AttribDict object.

Axis._repr_pretty_(p, cycle)

Special Methods

Axis.__bool__()
Axis.__contains__(key)
Axis.__delattr__(name)
Axis.__delitem__(name)
Axis.__dir__()

Default dir() implementation.

Axis.__eq__(other)

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

Axis.__format__(format_spec, /)

Default object formatter.

Axis.__ge__(value, /)

Return self>=value.

Axis.__getattr__(name, default=None)

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

Axis.__getattribute__(name, /)

Return getattr(self, name).

Axis.__getitem__(name, default=None)
Axis.__gt__(value, /)

Return self>value.

Axis.__init__(*args, **kwargs)
Axis.__init_subclass__()

This method is called when a class is subclassed.

The default implementation does nothing. It may be overridden to extend subclasses.

Axis.__iter__()
Axis.__le__(value, /)

Return self<=value.

Axis.__len__()
Axis.__lt__(value, /)

Return self<value.

Axis.__ne__(other)
Axis.__new__(**kwargs)
Axis.__nonzero__()
Axis.__reduce__()

Helper for pickle.

Axis.__reduce_ex__(protocol, /)

Helper for pickle.

Axis.__repr__()
Axis.__setattr__(name, value)

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

Axis.__setitem__(key, value)
Axis.__sizeof__()

Size of object in memory, in bytes.

Axis.__str__(force_one_line=False)

Fairly extensive in an attempt to cover several use cases. It is always possible to change it in the child class.
