how to go from the recorded waveforms to SAC files
2023-03-20 05:32:22
Hello Sir or Madam:
I am trying to use your SAC files. I often download miniseed files and
convert them into SAC files. Please allow me to ask a basic question that
I searched on your website but didn't find. A station that records seismic
waveforms usually lasts for hours or days, could you please tell me how
IRIS cut these waveforms into SAC files? A method I can think of is the
STA/LTA method, could you please confirm if that is the method you utilized?
Thank you very much!

    Hi Rui Zhou-

    Thank you for your interest. Am I correct that you received data from IRIS Web Services in SAC format? I am trying to understand the context of your question, as it sounds like it does not relate to the SAC software.

    Since you mention the STA/LTA method, is the data you received based on phase arrivals at stations from an earthquake?

    I look forward to hearing more about what process you are following.

    Thanks,

    -Rob
