Contrasting projected and observed rotational velocities for the real samples using K = 2 (Coma Berenice and Tarantula samples) and K = 3 (Geneva sample) for MSA algorithm. Gray bars correspond to Histograms of the projected rotational velocities for the real samples. The blue line represents the corresponding estimated f_Y(y|β) using MSA. The black dashed-dotted line represents the corresponding estimated f_Y(y|β) using TRM.
