I have installed a Reftek 151-120 sensor with a DAS 130. In order to plot
the noise curves I need to create the poles and zeros file. Reftek provided
me the poles and zeros but I don't understand how to calculate the constant
for the PAZ in SAC format. Acoording to what I read and my maths, the
constant is +7.623696e+16 but when I plot the noise curves they do not seem
correct because below 0.004 Hz the slope is positive, and the horizontal
components exceed the NHNM till 0.05 Hz. Can anybody help me? Thank you for
your time!
