release notes: ============== Features - consistent manual phase picking through predefined SNR dependant zoom level - uniform uncertainty estimation from waveform's properties for automatic and manual picks - pdf representation and comparison of picks taking the uncertainty intrinsically into account - Richter and moment magnitude estimation - location determination with external installation of [NonLinLoc](http://alomax.free.fr/nlloc/index.html) Known issues - Magnitude estimation from manual PyLoT takes some time (instrument correction)
