TL;DR: In this paper, the authors used observations from the Dark Energy Survey (DES) from 2012 November until 2016 February, amounting to 4,292,847 charge-coupled device (CCD) frames and recovered 202 TNOs and Centaurs, 63 of which have been discovered by the DES collaboration as of the date of submission.
