24. We have considered the influence of the time-independent instrumental response function. For the case of two interconverting structures with Gaussian intensity profiles, it can be ,shown that instrumental broadening only modifies the widths, but structural isosbestic points remain robust.

34. The disparity in yield for the 5- and 27-ps time regimes may suggest that the dynamics involve bifurcation with two types of trajectories: those that are direct and lead to a large c-axis structural change (low yield) and those that concurrently involve expansion and lattice relaxation (high yield) (33).
35. The anisotropy of expansion has been addressed in detail in (21). In this case, the sample is free to expand along the surface normal direction, whereas in a-b planes, the laser-excited region is constrained by the surrounding unexcited region. Moreover, for in-plane charge transfer, the Coulomb repulsion is mainly interplanar, which results in a substantial expansion along the c axis with essentially no lattice change in the a-b planes.
