Not sure about that Peter. Absolute QEs are quoted for a few Sony sensors on the Point Grey site - understand they do their own measurements.

I often ask myself of anything I read on the net "Does that seem reasonable", with a touch of Cal Sagan's "extraordinary claims require extraordinary evidence"
Point Grey's "measured" QE for the Sony IX674 is 70% at 385nm....amazing !!! since that beats the very best (and very expensive...they fly similar sensors on Hubble) E2V back illuminated CCD's currently available. I'd suggest Point grey got absolute vs relative QE's confused....
One wonders if they used a rain gauge
