# obspy.core.event.magnitude.StationMagnitude

class `StationMagnitude`(force_resource_id=True, *args, **kwargs)

  Bases: `obspy.core.event.base.__StationMagnitude`

  This class describes the magnitude derived from a single waveform stream.

  Parameters: | resource_id (`ResourceIdentifier`, optional) Resource identifier of StationMagnitude. 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. origin_id (`ResourceIdentifier`, optional) Reference to an origin’s `resource_id` if the StationMagnitude has an associated `Origin`. mag (float) Estimated magnitude. mag_errors (`QuantityError`) AttribDict containing error quantities. station_magnitude_type (str, optional) See `Magnitude` amplitude_id (`ResourceIdentifier`, optional) Identifies the data source of the StationMagnitude. For magnitudes derived from amplitudes in waveforms (e.g., local magnitude ML), amplitudeID points to publicID in class Amplitude. method_id (`ResourceIdentifier`, optional) See `Magnitude` waveform_id (`WaveformStreamID`, optional) Identifies the waveform stream. This element can be helpful if no amplitude is referenced, or the amplitude is not available in the context. Otherwise, it would duplicate the waveform_id provided there and can be omitted. comments (list of `Comment`, optional) Additional comments. creation_info (`CreationInfo`, optional) Creation information used to describe author, version, and creation time.

  Note

  For handling additional information not covered by the QuakeML standard and how to output it to QuakeML see the ObsPy Tutorial.

  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.

  `__delattr__` |
  `__delitem__` |
  `__dir__` | default dir() implementation
  `__eq__` | Two instances are considered equal if all attributes and all lists
  `__format__` | default object formatter
  `__getattr__` | Py3k hasattr() expects an AttributeError no KeyError to be
  `__getitem__` |
  `__getstate__` |
  `__init__` |
  `__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
  `__setitem__` |
  `__setstate__` |
