Fig 6   Spatial imaging and energy resolution of an imaging strip detector with a Ta absorber, shown schematically in Fig 2.   The energy width is 13 eV, using fitting to the broadened line structure of the K_a1 and K_a2 pair of lines of the ⁵⁵ Fe source. Many different grid spacings (energy binnings) were used and the results for D E for each grid spacing were averaged to avoid any false results due to binning of the data.
