The decays DsD+K0SD0π+K0S are used to measure the helicity angle, i.e. the angle between the pion and kaon in the rest frame of the D. The decays of Ds1(2700)+ and with mass 2.8 GeV were measured. It is unclear if this is the Ds1(2860)+, Ds3(2860)+ or a mixture of the two. This histogram is therefore filled we with each state and the admixture. The data were read from the plots in the papers.
