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! Rui Zhou

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 Abderrahim BOULANOUAR
