Parameters

  • trace (Trace) – Trace object to append to this RtTrace

  • max_time (float) – Maximum time in seconds after ref_time to apply Mwp integration.

  • ref_time (UTCDateTime) – Reference date and time of the data sample (e.g. P pick time) at which to begin Mwp integration.

  • mem_time (float, optional) – Length in seconds of data memory (must be much larger than maximum delay between pick declaration and pick time). Defaults to 1.0.

  • gain (float, optional) – Nominal gain to convert input displacement trace to meters of ground displacement. Defaults to 1.0.

  • rtmemory_list (list of RtMemory, optional) – Persistent memory used by this process for specified trace.

Return type

NumPy numpy.ndarray

Returns

Processed trace data from appended Trace object.
