The haloes in our study range in mass from $\\sim 10^{10}$ to $\\sim 10^{12} \\mathrm{M}_\\odot$, and are resolved with $10^5$ to $10^7$ particles. We fit the spherically averaged density profiles of DM haloes with the three parameter Einasto function. For our sample of haloes, the Einasto shape parameter, $\\alpha$, is uncorrelated with the concentration, $c$, at fixed halo mass, and at all redshifts.
