The MN plugin is designed to compute the Canadian Nuttli magnitude
according to the Geological Survey of Canada.

Description
===========


The amplitude unit in SeisComP3 is **meter/second** (m/s).

Settings
--------

Add the *nuttli* plugin to the list of loaded plugins and set the region-specific
calibration parameters in the global configuration. E.g. in the global module
configuration:

.. code-block:: sh

   plugins = ${plugins},nuttli

Amplitude time window parameters and magnitude corrections are configurable in the
global bindings.

Add the Nuttli magnitude type to the range of magnitudes for which the amplitudes are
to be calculated, e.g.:

.. code-block:: sh

   amplitudes = ML,MLv,mb,mB,AMN

.. note::

   Provide *AMN* for computing Nuttli-type amplitudes.

   magnitudes = ML,MLv,mb,mB,MN

Configuration
=============


.. confval:: amplitudes.MN.velocityModel

   Type: *string*

   The travel time table set compiled for LocSAT. The tables
   are located in \"share\/locsat\/tables\/[vmodel].\*\".
   Default is ``iasp91``.

.. confval:: magnitudes.MN.region

   Type: *path*

   The path to the BNA file which defines the valid region
   for the MN magnitude. Note that the entire path from
   source to receiver must lie entirely within the polygon\(s\).
   Default is ``@DATADIR@/magnitudes/MN/MN.bna``.
