Subject: cutting sac files on time

Hi,
I just want to cut sac files only by giving exact time. I use to sign to put T0 and then cut from T0 but always have problems to see exact peak to cut, so I just want to give exact time to cut without putting T0 . is it possible to cut files only by giving exact times.
thanx

    Hi Mehmet,

    You must to use the cut command, using in this way:

    sac> cut t0 t1
    sac> read file
    sac> plot
    sac> synchronize
    sac> plot

    In the second plot you see the time windows of cut, the "exact" time
    depend of your sampling rate, in other words, if you have 100 s/s
    you cant cut for example to=0.00 to t1=10.00, remember that the independent
    variable is t in seconds, so your cut resolution is 1/100 of second.
    Try cut 0.01 10.00 and cut 0.02 10.00, small values no works.

    HTH,

    Milton

        Hi Mehmet,
        If i understand your question correctly,
        you must to define a "marker" or reference, for example if your time
        17:22:43.5 is the Origin time, you define the O variable in the sac
        header file prior the use of the cut command, after call the cut command,
        If you time 17.. is the start time of file use B, see the cut help.

        You can give data points using the N reference.

        HTH,

        Cheers,

        Milton
