(a) Comparison of adapted experimental data from Blevis et al. (see Ref. 40), simulated planar PHS results under Blevis conditions and with reduced ENC values. (b) Count-rate linearity planar a-Se with $150\text{-}\mu \mathrm{m}$ planar Se, $32\text{-}\mu \mathrm{s}$ shaping time, and $1{\mathrm{mm}}^2\text{pixel}$, exposed to 59.5-keV x-rays.
