Table 3

Best-fitting internal helium spread, δY, and fraction of He- enriched stars, f_2P .

Cluster	δY	f_2P	δY	f_2P
Hodge 11	≥0.12	84%	0.10	46%
NGC 1841	0.11	60%	0.08	40%
NGC 2210	≥0.12	86%	0.09	52%
NGC 2257	≥0.12	76%	0.09	48%

Notes. The values in second and third columns are based on the assumption that the δY distribution is flat, while the fourth and fifth columns are based on the assumption that the δY distribution is bimodal.
