TL;DR: A new software package for modeling the point-spread function (PSF) of astronomical images, called Piff (PSFs In the Full FOV), is introduced, which is applied to the first three years of the Dark Energy Survey data.

TL;DR: In this paper, a comparison of different approaches to star-galaxy classification using the broadband photometric data from Year 1 of the Dark Energy Survey is performed by performing a wide range of tests with and without external 'truth' information, which can be ported to other similar data sets.
