When obtaining data using a client (such as iris through obspy.fdsn), how do I get the azimuth of the different components? For Channels NEZ, this isn't a problem of course.
For BH1 and BH2 channels with arbitrary orientations, however, how do I obtain the azimuth of each component (using obspy.fdsn.client.get_waveform for instance). Is this information contained in the Stream or Trace? Extracting this same data from a SEED volume typically fills in the CMPAZ header value.
Thanks very much,
