Hi,
I am trying to remove the instrument response from the data using
transfer function as shown below:
SAC> r 2010.332.14.48.FS12.BHZ
SAC> rmean
SAC> transfer from polezero s FS12_ZVBB.zp
ERROR 1:
My pole-zero file for station FS12 is
CONSTANT 3.605e+17
ZEROS 2
0.00E+00 0.00E+00
0.00E+00 0.00E+00
POLES 5
-3.701E-02 3.701E-02
-3.701E-02 -3.701E-02
-1.131E+03 0.000E+00
-1.005E+03 0.000E+00
-5.027E+02 0.000E+00
I am unable to understand why this error is appearing. Though I am
following the same format for pole-zero files for rest of the stations in
my network but SAC is having problem only with few stations. I have double
checked the response files from the IRIS, DMC website for this station
(FS12) and all the values are exactly the same as it is in my pole-zero
file. I would really appreciate your advice.
Thanks
