Notes. Binary fraction for Draco, Ursa Minor and Sculptor using the methodology from S18. Columns 1 and 2 list the galaxy name and the source of the result, respectively; Col. 3 indicates the binary fraction obtained, Cols. 4–6 list the uncertainties for confidence levels of 1σ, 2σ, and 3σ. It is important to note that the results for Ursa Minor and Draco share the same methodology as well as the same dataset. For Sculptor instead, the S18 methodology is applied to the Sculptor data presented in Sect. 2.1.
