astropy-based cross-match is more than 13x faster than the bespoke for loop was, with no change to the resulting scatter plot
note that if a reviewer wishes to re-run this whole notebook end-to-end, they would need to have created the relevant custom coadd first, and (assuming that the required custom coadd exists) the end-to-end run time of this notebook should be in the 10-15 minute range
