Notes. We give the enclosed masses at 300 pc and unreduced χ2 statistics for our fits. As discussed in Sect. 3.1 the minimum β allowed is −3, and therefore all errors on one side are bound by this constraint (except in the case of Fornax). For instance, the lower error bar on β reaches in most cases −3, which is not the 1-σ error bar but the error bar at the χ2 in the brackets. The same applies to ρDM,o and rDM. Related to this, the one sided error bars for Carina arise because the best fit is found at β = −3.
