Perfect! Yes, this is the one I was looking for. An thanks for the URL for sensitivities results. I didn't know about that page.
ALSO ... does anyone know why the units for strain on this graph are represented as: h per sqrt(Hz)? I've never seen that explained anywhere, but the sensitivity graph is always shown this way.
That's the unit of the root-sum-square strain amplitude .... which doesn't mean that much to me but given your background in physics this might ring a bell :-)
AFAIK this unit for sensitivity is more meaningful than the raw displacement as it this one allows to better compare a given waveform to the detectors sensitivity characteristics...but really someone with better physics skill should try to answer this.

It sounds analogous to the RMS (root-mean-square) method of measuring alternating currents, sounds, or other wave phenomena. Where a value oscillates (or wanders randomly) around zero, if you just take the mean of a set of measurements they tend to cancel out, telling you little about the amplitude (or range), but by first squaring them—or perhaps taking the absolute value—you get a better picture of the signal, so to speak.

Is that what you are looking for?
