Description
The Gaia catalogue, providing positions and proper motions of stars as faint as 21 mags, has been revolutionary in Galactic astronomy and other subfields. Using the DESI Legacy Imaging Survey, our goal is to extend our data to stars as faint as 27 mags. To do so, we have been working on correcting for systematic errors in the Legacy data, including tree rings, differential chromatic refraction, and lateral color.
