438 438  The 1C nodes seem to have the same response as the 3-channel IGU-16HR-3C (above), however the response posted at IRIS-NRL seems to imply that there is no poles and zeros information (e.g. a flat/linear response). This is 100% not so.

454 454  Below the corner frequency 0.2 Hz (i.e. 5 seconds) the response still does a good job, but may need to be dialed in a bit. We are looking into this.
