            * https://github.com/iLCSoft/ILDConfig/blob/master/StandardConfig/production/Documentation/HowToRunBgOverlay.md#running-the-reconstruction-with-the-overlay-background?
    * k4Reco: DDPlanarDigi updated, danger of random number sequences aligning if not super carefully choosing our random seeds?
        * Probably not? But reproducibility is more important
