global Duration magnitude plugin Duration magnitude plugin Default filter type to use before processing and after deconvolution. It's possible to set : 1 for a Wood-Anderson seismometer 2 for a 5sec generic Seismometer 3 for a WWSSN LP seismometer 4 for a WSSN SP seismometer 5 for a Generic Seismometer 6 for a Butterworth Low pass filter 7 for a Butterworth High pass filter 8 for a Butterworth Band pass filter 9 for a 1Hz eigen-frequency L4C seismometer taper applied to the signal signal length used to compute the duration magnitude Butterworth filter parameter applied to the signal Maximum depth at which duration magnitude is valid Maximum distance between earthquake and station at which duration magnitude is valid Signal to noise ratio below which the coda is reached Maximum expected duration magnitude value This is used to find how much data should be loaded for a given station by reversing the formula FMA regional coefficient See Hypo2000 manual FMB regional coefficient See Hypo2000 manual FMD regional coefficient See Hypo2000 manual FMF regional coefficient See Hypo2000 manual FMZ regional coefficient See Hypo2000 manual Linear correction Offset Station correction
