Constraints on the dark-matter density profile of Eridanus 2 in the computational (left) and astrophysical (right) parametrizations, assuming FDM, found using CJAM and MultiNest. Units are omitted for clarity. The parameters are the dark-matter density of the CDM-like outer profile at 100 pc (ρCDM, 100), the logarithmic slope of the CDM-like outer profile at 100 pc (αCDM, 100), the soliton radius (rsol) in kpc, the scale radius (rs) of the CDM-like outer profile in kpc, the ratio of the dark-matter density at the transition between inner and outer profiles over the central soliton density (ε), the characteristic dark-matter density of the CDM-like outer profile (ρCDM, 0) in M⊙, kpc−3, the central dark-matter density of the soliton (ρsol, 0) 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 (without arrows) or the 68% and 95% confidence limits (upper and lower arrows, respectively).
