Data supplement to: Quality control of image sensors using gaseous tritium light sources

In the article “Quality Control of Image Sensors using Gaseous Tritium Light Sources” (https://doi.org/10.1098/rsta.2021.0130) we propose a practical method for radiometrically calibrating cameras using widely available gaseous tritium light sources (betalights). This dataset includes all the recorded data along with the scripts necessary to reproduce the results and figures.
