#!/usr/bin/env python # -*- coding: utf-8 -*- """ PyLoT: Main program =================== PyLoT is a seismic data processing software capable of picking seismic phases (symmetric and asymmetric error assignment), exporting these to several common phase data formats and post process the data, e.g. locating events, via external localization software. Additionally PyLoT is meant as an interface to autoPyLoT which can automatically pick seismic phases, if the parameters have properly been chosen for the particular data set.
