Time-resolved two-photon fluorescence microscopy images for ST-SPPs

This dataset contains the fluorescence imaging data used in the manuscript “Observation of space-time surface plasmon polaritons.”timeresolved: time-resolved image stacks used to generate supplementary movies and group-velocity estimation.spatialdistribution: fluorescence micrographs at fixed positions/delays used to obtain spatial profiles as in Fig. 4.Files follow the naming convention gXXXX_XXs_d[m/p]XX, where XXXX is the CCD gain, XXs is the exposure time in seconds, and d[m/p]XX indicates the delay step (e.g., <code>g3700_40s_dp50</code> means gain = 3700, exposure = 40 s, delay = +50 steps). Note that the “delay step” refers to the delay stage step, not a delay time; 1 step corresponds to 100 nm of stage travel.
