Notes. The fits are to a model of the form v(φ) = v0 + KW·sin [ 2π(φ − Δφ) ]. Parameters without uncertainties were held fixed in the fit. KW – amplitude of the sine curve; v0 – offset of the sine curve, Δφ – phase shift: v0 = −7 km s-1 and Δφ = 0 are fixed to the orbital motion of the black hole. Best fits are printed in bold.
