The galactic globular cluster system - Calibration of the ratio R = N(HB)/N(RGB)
On the basis of Synthetic Horizontal Branches computed with Sweigart and Gross (1976) Horizontal Branch evolutionary tracks, and by means of Sweigart and Gross (1978) Red Giant Branch star models, the calibration of the ratio R = N(HB)/N(RGB) in terms of helium abundance (Y), He-core mass (Mc) and Horizontal Branch morphology is derived.
