Proposed discrimination of photon numbers is based on sum-squared error between an individual detector response curve and a calibration suite of response templates corresponding to a range of photon numbers. Templates for low numbers are obtained directly from data. Templates for higher photon numbers are extrapolated from fits describing incremental differences between successive low-number response templates.
