Anode energy spectrum of photon interactions 3 mm (C/A ratio = 0.53) from the anode plane where the total energy per event is summed over (a) any one or (b) up to two anode strip signals. An uncollimated ²²Na source was used to irradiate the edge of the 5 mm thick detector. The spectra have been corrected for depth-dependent signal deficit along the DOEP, and the error bar corresponds to the 95% confidence interval of the fitted parameters.
