A comparison of the systemic PMs for our dwarf galaxy sample between this work and Battaglia et al. (2022), for each coordinate on the sky. The results are in adequate agreement. Our new uncertainties are generally smaller. This plot does not include our HST-HST PM results or the IC 10 PM from Brunthaler et al. (2007).
