TL;DR: The DES data management (DESDM) system as discussed by the authors is used to process and archive the Dark Energy Survey (DES) data and the resulting science ready data products, which are available to the Collaboration and later to the public through a virtual-observatory compatible web portal.

TL;DR: This work introduces an experimental method of reducing PSF variation effects within coadded images by bringing all images to a common PSF both within an image and from image to image within a coadd tile by applying position-dependent smoothing kernels determined using power spectrum weighting functions.
