I would first like to thank the contributors to this subject matter for
their input.

Photometrics would like to provide information and actual data which should
help answer the points raised and discussed. This can be found at:

http://www.photomet.com/useroutreach/042210.php 

We discuss measuring analog gain i.e. the cameras e/ADU conversion factor
using a mean-variance analysis, how to calculate electron multiplication
gain and the ‘flatness’ or photo-response non-uniformity. We also explain
that Rapid-CAL and Quant-View features of the evolve camera utilize a
combination of these measurements to provide accurate data integrity.

We hope this data and information helps clarify some of the questions being
asked and we are always happy to answer any questions you may have.
