pyrocko.multitrace

Multi-component waveform data model.

Classes

MultiTrace([traces, codes, data, tmin, deltat])

Container for multi-component waveforms with common time span and sampling.

class MultiTrace(traces=None, codes=None, data=None, tmin=None, deltat=None)

Bases: Object

Container for multi-component waveforms with common time span and sampling.

Instances of this class can be used to efficiently represent multi-component waveforms of a single sensor or of a sensor array. The data samples are stored in a single 2D array where the first index runs over components and the second index over time. Metadata contains sampling rate, start-time and CodesNSLCE identifiers for the contained traces.

Parameters:

traces (list of Trace) – If given, construct multi-trace from given single-component waveforms (see get_traces_data_as_array()) and ignore any other arguments.

♦ codes

list of pyrocko.squirrel.model.CodesNSLCE objects, default: []

List of codes identifying the components.

♦ data

numpy.ndarray (pyrocko.guts_array.Array)

Array containing the data samples indexed as (icomponent, isample).

♦ tmin

pyrocko.util.get_time_float (pyrocko.guts.Timestamp), default: str_to_time('1970-01-01 00:00:00')

Start time.

♦ deltat

float, default: 1.0

Sampling interval [s]

property tmax

End time (time of last sample, read-only).

get_trace(i)

Get single component waveform (shared data).

Parameters:

i (int) – Component index.
