At Doug's request, I am forwarding several curve sets
covering the relative evaluation of AEL and SAGE Laboratories
crystal holders. The curve data is in very rough form in the
sense that it represents a direct translation of measurements to
laboratory-type curve information, but I am sure that it will meet
your immediate needs. No particular significance is to be attached
to absolute sensitivity indicated by this set of measurements, but
relative sensitivities are fully significant.
