Hi Rui Zhou-
I don't see anything in the header relating to an event latitude or longitude or similar, so this must be just a time slice from this channel. It has a scale value which should be equal to the sensitivity of the instrument.

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!

Re: how to go from the recorded waveforms to SAC files - Rob Casey - 2023-03-21 11:05:27

Hi everyone,
I hope you are doing well.
I am using the FORTRAN 77 program to obtain Coda attenuation. The program
is written with an old SAC version. When I use the new version, I got error
(please see the attachment). Now, I need an old version of SAC like v101.5c
Linux 64 bit or less to solve the problem.
I hope somebody can help me by sending an old SAC version that can use in
Ubuntu 64 bit.
Thanks in advance
