problem in RSAC1
2009-11-11 20:57:49
Hi all

I have a simple question. While using rsac1 which is for evenly spaced
file, what does evenly spaced means ??? is it evenly spaced sample
data or what?
another question is i am making some changes in header like the time
of the origin of an event and using wsac0 but after that for some
data (not all) it is saying that "data not evenly spaced" when am
again using the rsac1 cmd.
do i need to use : CALL SETLHV ('LEVEN', .TRUE.,NERR) to counter this problem?

    A time series with a digitizing rate of 1 sps is an example of an evenly
    spaced data set. All one needs is "dt" to specify the common spacing.
    One does not need to specify the values of the "X" array.

    another question is i am making some changes in header like the time of
    the origin of an event and using wsac0 but after that for some data (not
    all) it is saying that "data not evenly spaced" when am again using the
    rsac1 cmd. do i need to use : CALL SETLHV ('LEVEN', .TRUE.,NERR) to
    counter this problem?

    That I do not understand. If others cannot help I suggest you post a set
    of SAC> commands that give you that result. Include an lh.
