Thread: Poles and Zeros

Dear SAC users

I am working on data from a list of seismic stations which have
different types of sensors: CMG-40, CMG-3T-120s, CMG-3ESP, STS-1, and
STS-2. I need to remove the instrument response from SAC files. I
could get information on Poles and Zeros data. However, I could not
find enough information about the normalizing factor and hence, how to
calculate the CONSTANT value.
If any one has information about the CONSTANT of these sensor types, I
will appreciate it!

Regards!
