Comparison of the parameters of the best-fit coreNFW models to the cosmological halo mass-concentration relation from Dutton & Macciò (2014; left) and the stellar mass-halo mass relation from Behroozi et al. (2013; right). Colours are as in Fig. 5. The triangle represents the best-fit model for NGC 3741 from a fit with the core radius as a free parameter (see Sect. 5.3). The black dashed lines show the mass-concentration relation from Macciò et al. (2008) and the stellar mass-halo mass relation from Moster et al. (2010).
