Numerical results are presented for evaluation of the convex optimization method designed for POVM (positive-operator-valued-measure) estimation of a photon-number-resolving detector (superconducting transition edge sensor). We discuss the accuracy degradation related to shot noise due to the finite measurement time of photon detection.
