<div>Normalized tube spectrum, prefiltered with 0.9 mm Ti and 3.5 mm Al. Shown are the sensitive ranges of the low bin (blue, solid line) and the high energy bin (green, dashed line) for the ideal (a) and the realistic ((b)–(d)) two-bin PCD, respectively. The energy resolution in the plots is 1 keV.</div>
