Comparison of the uncertainties on the best-fit parameters of our astrometric model obtained when using the full unWISE + Spitzer + HST dataset versus using only the Spitzer + HST data. Uncertainties on the reference coordinates (top panel) are greatly improved when omitting unWISE data, while those on proper motion (middle panel) and parallax (bottom panel) are mostly unchanged. Objects with more uncertain proper motions (i.e., σμ > 15 mas yr−1) or parallaxes (i.e., σϖ > 10 mas) show the largest deviations from the identity line (dashed line).
