Input file specification
The application requires a Miniseed Waveform (or any subtype) containing seismograms on which the wave arrival time should be detected. The waveform has to contain E, N and Z channels for each station.

Filling form values
The application form consists of four parameters - see Figure 2. The first parameter allows you to choose weights obtained by training the Machine Learning model, where the Original option are the original weights published by the authors of the models ([1] for the GPD model and [2] for the PhaseNet model), and all the others are weights obtained for public data described in [3]. The Stride parameter sets the stride in samples for point prediction models, and the P phase threshold and the S phase threshold set the threshold of probability for which the phase is detected.
