Figure 16.

Intensity of the negative signal induced in pixels surrounding the pixel under investigation. The direct neighboring pixels (L/U/R) show negative signals which on average reach around –10% or –4 keV of the incoming photon energy of 40 keV. The diagonal neighboring pixels (UL/UR) still exhibit negative signals down to around –5% or –2 keV. Even pixels further distant (RR/URR) show slightly negative mean values. It is obvious that the negative signal in the adjacent pixels is caused by photons absorbed close to the readout electrode, validating the assumptions previously made in the paper. Please note: Compared to Figure 14, where the pixel response is shown as function of the absorption position in the pixel itself, this plot indicates the pixel response of a pixel in the vicinity of the irradiated pixel as function of the absorption position within the pixel which is being irradiated.
