METHODOLOGY: The hardware required to reproduce the results - Andor iStar gen III intensifier ICCD, Perkin Elmer SPAD, JDSU Xcyte 355nm 100 mW laser. The software used to run the experiment and generate the data was National Instruments Labview version 2014. The raw data files are found in each zip folder, where each ASCII file is one frame read out from the camera. The labview project file included in the folder “Average and threshold” contains the VI’s necessary to threshold and accumulate the individual frames used in each of the figures in the paper.
