Hi Tobias, Lion and others!
After having been absent for quite a while, I have tried to browse through the archive to check if there had been a thread on this, but I could not find any, so I’d like to raise the following questions (using ObsPy version 1.0.1) and I’d be happy if someone can help me out.
After years of playing around with synthetics and non-seismological data, I am currently working on real world seismometers…so I have to correct the raw data collected with two different instruments for the respective responses - however, I struggle in both cases.
In the first case I have a classical table from the instrument calibration with values for
“frequency”, “amplitude (in V/m/s)”, “phase angle”
together with the recorder scaling value of X counts/(V/m/s).
Is there perhaps any function within ObsPy to carry out the correction from this directly or to fit a complex valued function in order to obtain a “Poles/Zeros/Gain” set?
In the other case I have given GSE2 calibration files that I also use in SEISAN. With these I run into the following error
