Categorization of noise.

	Type of noise

Noise source	Independent noise (A_noise)	Distributed noise (δ_A)	Proportional noise (kA_light)
Scintillation crystal	None	None	Poisson variance in number of light photons produced from each interaction—modeled in Matlab
			Secondary scintillator effects—modeled in Matlab

PSAPD	None	Leakage current shot noise—modeled in FEM (Verilog-A)	Shot noise due to light signal—modeled in Matlab
		Thermal noise from resistive sheet—modeled in FEM (H-SPICE)	Poisson variance in PSAPD gain—modeled in Matlab
			Excess noise factor—modeled in Matlab

Electronics	RENA-3 ASIC thermal noise—modeled in Matlab	None	None
