RAR for the central galaxies of clusters, subclusters, and groups. For each galaxy, three estimates of the net acceleration are given, depending on the anisotropy parameter (see Sect. 2). The error bars comprise all uncertainty in galaxy distances, stellar mass-to-light ratios, and uncertainties from the number of dynamical tracers employed. They are compared to the RAR of spiral galaxies from the SPARC sample (McGaugh et al. 2016), and to the relation found by Tian et al. (2024) for central galaxies of clusters. Shaded areas show the 1σ measured scatter. The numbers in the top-left corners indicate the rank of the galaxy in Table 1. Galaxies with asterisks in their name show signs of ongoing interactions. The short vertical red bar in each panel indicates one effective radius of the galaxy (BSR19).
