I received seismic data for which I would like to remove the instrumental response. The only information I have is that they were recorded on a Trillium broadband seismometer with a cutoff period of 40s.
I assumed it referred to the trillium 40 for which I found the following user guide. Some information is given about poles and zeros at pages 40-41 but it is unclear to me which one I should use. Besides, I intend to manually define them using Obspy but I am not entirely sure of how to do it.
At this point, I was planning to copy this example.
