pickax.seismogram_iterator

Module Contents

Classes

SeismogramIterator	Seismogram iterator that can move to next or previous. Optionally, may provide access to station and quake iterators, if used internally.
MDLSeismogramIterator	Seismogram iterator over a obspy mass downloader directory.
CacheSeismogramIterator	Very simple cache, remembers prev, curr and next data for up to size items
FDSNSeismogramIterator
ThreeAtATime	Iterates over a sub-SeismogramIterator grouping the resulting seismograms into three-at-a-time components of motion. So a station with a seismometer and a strong motion would be split into 2 iterations, first the HHZ, HHN, HHE channels and then the HNZ, HNN, HNE channels.

class pickax.seismogram_iterator.ThreeAtATime(sub_itr)

Bases: pickax.seismogram_iterator.SeismogramIterator
