    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.
