[SAC-HELP] Response file in sac format

[Arthur Snoke]

There are different versions of "sac response files."  One is the 
pole-zero file.  you should be able to get these files either from the 
IRIS database or from a SEED volume that includes data from such 
instruments.

Here is a pole-zero file from a station that I think has a CMG-3T sensor 
in the format understood by SAC.

ZEROS 3
POLES 5
-0.0370  0.0370
-0.0370  -0.0370
-502.7000  0.0000
-1005.0000  0.0000
-1131.0000  0.0000
CONSTANT 1.091252e+18

The constant should -- at least in principle -- be fine-tuned via a 
calibration.  This is for a vertical component, but I think it will be 
the same for the horizontals.
