+MLh
+###
+
+The MLh plugin (previously MLsed) is designed to compute amplitudes
+and magnitudes according to the Swiss Seismological Service (SED)
+standards.
+
+Description
+===========
+
+Amplitude
+---------
+
+The MLh amplitude calculation is very similar to the original :ref:`ML<global_ml>`.
+The two differences are:
+
+- It uses the maximum of the two horizontal components (average can be configured if necessary)
+- It uses zero-to-peak in stead of peak-to-peak values
+
+Zero-to-peak is calculated by just dividing the peak-to-peak amplitude by two.
+This is not exact for unsymmetrical signals, but that doesn't matter because the
+code actually generates zero-to-peak amplitudes internally and multiplies them
+with two. So in the end we get real zero-to-peak values.
+
+Station Magnitude
+-----------------
+
+The MLh plugin calculates the individual station magnitude using the following formula:
+
+.. math::
+
+   mag = \log10(waamp1) + A \times hypdistkm + B
+
+waampl is the amplitude produced by the MLh plugin. Hypdistkm is the distance
+from the sensor to the hypocenter in kilometers. A and B are parameters that
+can be configured in a config file. Several pairs of A and B can be configured
+for different ranges of hypocenter distance.
+
+* Amplitude unit in SeisComP: **millimeter** (mm)
+* Time window: 150 s by :ref:`scautopick` or distance dependent
+* Distance range: 0 - 20 deg
+* Depth range: 0 - 80 km
+
+Network Magnitude
+-----------------
+
+To compute the network magnitude from station magnitudes the SED standard is applied
+by computing the median value of all contributing station magnitudes without any trimming.
+
+Configuration
+-------------
+
+Add the *mlh* plugin to the existing plugins in the global configuration.
+Set the calibration parameters in the global bindings to compute MLh.
+There exist no default configuration. Add MLh to the list of
+amplitudes and magnitudes in the configuration of :ref:`scamp` and :ref:`scmag` for computation
+and in :ref:`scesv` for visibility.
