Good afternoon

I am a SAC user and I have been trying to represent a group of sismograms in only one image but with a special condition.
All the sismograms are of the same event and all of them have the same X axis (with the time). In the Y axis I want to represent the epicentral distance and I wan to put my sismograms placed in their epicentran distance.
Is it posible to represent with SAC and use that conditions?
Thanks you for your help and your time.

    Dear Javier -

    You want to use the PLOTRECORDSECTION command in the SSS subprocess. These are some basic commands to help you get started; then you can adjust them for your own data.

    datagen sub regional *.z ;* Built-in data
    sss
    tw -10 400 ;* Define time window
    prs ;* Default record section plot

    Chapter 8 of the SAC book has a lot of examples of the use of the SSS subprocess.
