Fig. 6

One example of stripes (1″ width) used to extract count numbers, mean energies and spectra. In the bottom row, the projection onto the outflow direction (here assumed to coincide with the x-axis) is shown, the thick black line is the measured photon number, the thin blue dashed line indicates the mean photon number ignoring differences in the efficiency of the individual exposures. The red bars indicate the expectation value for a time constant emission, shown are the 70% and 90% probability ranges.
