Thread: Help me for record convertion

Hello,

When we use radial and tangential components we need
to convert E-W and N-S components. If the lengths or
sample numbers NPTS in E-W and N-S components are not
the same, sac2000 refuses to work. Could you possibly
tell me how to deal with this case?

In a directory, there are many records from many
stations. At some stations only E-W componets or N-S
components exist. In this case if we want to rotate,
sac2000 also refuses to work. Could possibly tell me
how to deal with this case?

I need to process many records at one time, and I am
trying to use sac macro to do the job.

Thanks in advance,
Shutian
