Example “bricks” covering 0.25 × 0.25 deg2 from the DECaLS survey (top row; brick 2212p085) and the MzLS and BASS surveys (bottom row; brick 1689p532). From left to right, the panels show the actual grz imaging data, the rendered model based on The Tractor catalog of the region, and the residual map. The Tractor catalog represents an inference-based model of the sky that best fits the observed data. Readers can explore the data, models, and residual images in more detail using the Legacy Surveys Imagine sky viewer at http://legacysurvey.org/viewer.
