Energy window: 250–650 keV, all entries. Measured values are without parentheses, calculated values are with parentheses. Calculated values for Resolution and Uniformity Fraction where obtained from Equations 1 and 3, respectively. Calculated values for Sensitivity were obtained from Equation 2 with α= 0.64 and ε= 0.77.
