“Hiding images in noise": Experimental data and analysis code S. Johnson, A. McMillan, C. Torre, S. Frick, J. Rarity, and M. Padgett http://dx.doi.org/10.5525/gla.researchdata.1362 Program and data for the production of the data within the publication for figures 2 and 3. The programs are written in MATLAB (R2021a). There are seperate files for the production of the date in figures 2 and 3. No additional functions are used outwith the base MATLAB package. The data files are individual frames from the Andor iStar camera. The aquisition for all frames was 1 second. The naming 'NoGate' indicted the acquisition used a long acqusition time and did not temporally filter the signal, the naming 'Gate' is for the heralding measurment where the temporal filter of 10 ns exposure is used for each trigger signal recived by the camera. The relative claibrated intensity is shown by the value followed by the frame number.
