Filtered TD maps at 171 (top), 193 (middle), and 211 Å (bottom). Oscillatory patterns obtained with an automatic Gaussian fitting are marked in red. The numbers shown are specifically related to the oscillatory patterns detected at 171 Å. The series of labels “p” refers to some segments of the patterns extracted and compared between 171, 193, and 211 Å, which are simultaneous and apparently from the same locations.
