Notes. The dynamic mass is taken from the Tully galaxy groups catalog (Tully 2015) and corrected down by 12%, as needed to convert the zero velocity mass to virial mass (Sorce et al. 2016b). Alternatively, we quote the masses inferred from scaling M_500c for Coma from the Planck data (Planck Collaboration X 2013), following Ragagnin et al. (2021) for converting the different masses or taking M_vir from the measured gas mass of Virgo, as obtained from Planck data (Planck Collaboration XL 2016). We also show the virial masses obtained in the SLOW, CORUSCANT, and SIBELIUS simulations, as well as the distribution from the 200 Virgo-like clusters from the LU2016 simulations (Sorce et al. 2020) and the radial velocity of the clusters in SLOW to be able to compare their radial distances (see also Sorce 2018 for the variance of the cluster properties in different CLONES realizations). We converted M_200c as given for the SIBELIUS simulation to M_vir following Ragagnin et al. (2021) and using the same cosmology as that used in the SIBELIUS simulation. A more detailed comparison of cluster properties from SLOW with observations will be presented in Hernández-Martínez et al. (in prep.).
