A few waveforms with negative S-P differential time

[sgrubas]

Hello Yangkang,

Thank you for the great dataset!

I've recently found that several waveforms seem to have the wrong P/S arrival samples.
Some of them have a negative or too small (S - P) difference. The figure with 18 examples is attached.

The list of the waveform IDs is also attached in the .txt file.

This is likely not a critical issue for the dataset, given its total size. I am just letting you know.

Best regards,
Serafim

Hi, Serafim, Thank you very much for finding these issues. They are very good feedback. We'll look into the reason for these wrong labels. We'll continue expanding the TXED dataset. The next version, hopefully, will be out in 2026, and we'll ensure these issues are resolved. Just keep us informed if you find any other issues. Thank you so much again! Best, Yangkang
