In this preliminary analysis we discuss on a statistical inversion method applied to the measured stellar Vrot sin i. Our goal is to obtain the Vrot of the cluster stars which is a key parameter of stellar evolution computations. We estimate rotation impact on the age determination of cluster stars using the Maeder-Zahn’s theory of stellar rotation in the Cesam2k code.
