        Dear Ron, Eric (and all),

        my understanding is that we are talking about different
devices serving different purposes.  The Colorado device - as
far as I know - is a genuine "tile mapper", measuring the
response as a function of where the light was produced (and
served for instance to optimize the path of the lightguide).

        The device Debrecen was asked to look into is what
I would call a "tile tester", a QA device to be used at the
factory, that would take the tiles just manufactured, run
overnight with cosmics (and maybe with LEDs the same way as
in the calibration system) - then based on their average
response whether the tile is acceptable for delivery or not.
