The MLr plugin is designed to use the MLv station amplitudes and provides a GNS/Geonet local magnitude (Jristau this study: - REF-). The magnitude uses a station correction term and the hypocentral distance Hard coded range are 0-20 degrees maximum distance, and 800 km max depth.
The MLr amplitude calculation is that of the Mlv amplitude computation
The MLr plugin calculates the individual station local magnitude using the following formula:
waampl is the amplitude produced by the MLr plugin. Hypdistkm is the distance from the sensor to the hypocenter in kilometers.
The GNS/Geonet Mlr local magnitude is using the default Sc3 behaviour for the automatic network magnitudes. Hard coded range are 0-20 degrees maximum distance, and 800 km max depth.
