Figure 3
(a) Two overlayed count-rate histograms as a function of gate delay for the `blue' and the `red' ROIs as indicated in (b). Dashed vertical lines indicate the `center of mass' (COM) position of the corresponding histogram. (b) PILATUS 100K photosensor area divided on a grid of 82 × 32 ROIs. The color code corresponds to the COM position of the single-bunch histogram. The statistical noise seen on the right-hand side of the photosensor area is due to the much lower X-ray photon hit rate in this region. |
