Removing the instrument response with no station metadata available

Usage Questions
1

Hi All,

After applying filtration and detrending, I want to use remove_response() on my SEG2 format data, but it asks for the inventory file while I do not have it. I know that I should attach the response to the trace with obspy.core.trace.Trace.attach_response(); Otherwise, it is not working. However, I have no clue how to do it. It would be great if somebody could help me figure out how to fix the problem (Here is the file: Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.).

Also, I do not get the necessity of having the water level in the remove_response code. Can anybody explain why that matters?

Thank you

You can not do response correction without information on what the response looks like. If it is industrial data it might be simple geophones and you could build a response from knowing the gain and the corner frequency (and dampening), but thats about it, I think.
