Figure 3
(a, b) Examples illustrating the two types of errors of photon assignment by the GG and PPC algorithms. (c, d) Photon position degeneracy. The numbers in white denote the pixel readout values assuming a single-photon ADU value of r1 = 151. Here all the examples are simulated assuming σr = 0 and σg = 0. The white circles, white `×' and black `+' are the real photon positions, and the estimated positions by GG and LSF separately. |
