I'd like to annotate seismometer data after processing with event time and P- and S-wave arrival times automatically. Is there some way to download phase arrival times for specific events and stations? The waveform plots on Wilbur 3 are annotated with phase arrival data; how can I get the times without having to copy and paste for every event-station combination?

    Hi Joshua,

    Wilber uses a simple phase arrival model based on distance and depth, the core package is here: https://www.seis.sc.edu/TauP/

    A version of this is also available as a web service: http://service.iris.edu/irisws/traveltime/1/

    Cheers,
    Adam
