CONTENTS ----------- File listing: data_fig1c.txt data_fig3a.txt data_fig3b.txt data_fig4_main_unpadded.txt data_fig4_main_padded.txt data_fig4_inset.txt data_fig5_raster_positions.txt data_fig5c.txt data_fig5d.txt data_fig5e.txt data_fig5f.txt The above files contain all data in the main manuscript. The origin for the raster images (data_fig5c to data_fig5f) is the bottom left element of the array. Additionally, we include two files of raw data from the raster image in figure 5c, which demonstrate the full 70 ps time window of the measurements (hence the 14.3 GHz frequency resolution of the sensor), for the interested reader: raw_data_fig5c_unloaded.txt raw_data_fig5c_loaded.txt The following files contain all data in the supplemental document: data_figS2a.txt data_figS2b.txt data_figS2c_raw.txt data_figS2c_smoothed.txt data_figS2d_raw.txt data_figS2d_smoothed.txt data_figS3_histogram.txt data_figS3_fit.txt data_figS4a.txt data_figS4b.txt All the above files are comma-delimited, and the first line describes the contents and units of the respective columns. 5. METHODS ---------- A detailed description of the experimental procedures and instrumentation, data collection, and data analysis are described in the related publication cited above in section 1.
