Notes. Logarithmic scatter of the scaling relations in Magneticum used as halo-mass proxies in the group regime. The proxies Y are reported in the left column and they are the BCG stellar mass, the total stellar mass, and the total luminosity in the r-band, respectively. All the masses are in units of M⊙, while the luminosity is expressed in L⊙.
