Constraints on the dark-matter density profile of Eridanus 2 in the computational parametrization, assuming CDM, found using CJAM and MultiNest. Units are omitted for clarity. The parameters are the dark-matter densities ρ₂ and ρ₃ at 100 pc and 150 pc, respectively, in M_⊙ kpc⁻³ and the systemic velocity (v₀) in km s⁻¹. The contours correspond to 0.5σ, 1.0σ, 1.5σ, and 2.0σ confidence levels, where σ is the standard deviation of a two-dimensional normal distribution. The vertical dashed lines in the one-dimensional histograms indicate the median and the 68% confidence interval.
