Explanation of the terms and definitions used in §3[link]. Left and right columns represent the different time ranges of the halo background and femtosecond sliced X-rays, respectively. The top plots show a typical dynamic response [{\cal R}(t)] (dark gray) of a model sample upon laser-pump. The center plots show the time structure [{\cal S}(t)] of the femtosecond sliced (red) and the halo background (blue) X-ray pulses. The green line is the sum of both contributions. The bottom plots show the corresponding signals [{\cal I}(t)] as detected in a model experiment. Clearly, due to the presence of the halo background, the green line shows quantitative and qualitative deviations when directly compared with the sample response function [{\cal R}(t)].
