METALLICITY DETERMINATION FOR A GLOBULAR CLUSTER BY SPECTRAL INDICES
초록
In order to determine the metallicity of a globuar cluster, M3,by using the spectral indices, a kind of index grid has been establshed by stars in globular clusters, M3, M15, M71 and old open cluster, NGC 188. The indices were measured from the medium resolution spectra of about
