Active Message Threads for March 2011
Hello,
I am trying to rotate two different components and then shift one of the
components by 1 sec, I am correcting for anisotropy. I have looked through
the sac manual and can not find a command to accomplish this time shift. Is
it the ADD command. My understanding is that ADD would increase amplitude,
not shift time. What is the command to shift a component by 1 sec ( ie move
each data point forward/backward by 1 sec. )? Any help would be greatly
appreciated.
Thank you,
C. Robert Lock

Hey guys,
I've got some researchers in my department who use SAC, and it is throwing a lot of errors. Are there cetain flavors of linux that SAC is not certified to work for, and others that it will work on, but not certified? I'll include some of the errors below.

Hello,
Several years ago, I tried making power-spectral-density plots for
noise characteristics of temporary seismograph stations, but it's been
many years since I did this, and I have forgotten the details. One of
my colleagues just sent me a copy of my original macro to ask me about
it, and I find myself second-guessing myself as to whether I did it
right originally. Here's the relevant section of the macro and my
query:
cut 0 1000

Hi,
I am with some problems when I'm using the transfer function. I've tried
with another computer with the same version of SAC and it's working. But in
my computer it appears the following error:
SAC> transfer from polezero s
SAC_PZs_IP_PMST_BHE__2009.091.00.00.00.0000_99999.9999.24.60.60.99999 to
none
ERROR 2110: Illegal option in POLEZERO file:
I don't understand the error. Can you help me with this problem?
Thanks a lot
Best Regards
Ana Domingues
