Figure 4
The observed probability of k = 1, 2 and 3 photons within a single pixel in SP mode as a function of mean photon density ([\bar{k}]). The dashed lines indicate the negative binomial distribution for β = 0.656. Photon density is divided into three regions according to the applied calculation methods for g(2). The inset shows [\bar{k}] as a function of Q with corresponding regions.
