obspy.io.stationxml.core._read_channel
- _read_channel(cha_element, _ns, level)[source]
Returns either a
Channel
object orNone
.It should return
None
if and only if it did not manage to successfully create aChannel
object which can only happen if one of the coordinates is not set. All the others are optional. If either the location or channel code is not set it raises but that is fine as that would deviate too much from the StationXML standard to be worthwhile to recover from.
