A Reinvestigation of the Possible Metallicity Spread in NGC 3201
We have conducted a reanalysis of the metallicity of six red giants within NGC 3201 on the basis of a new homogeneous set of spectra with resolution ∼30,000. Iron line strengths and the MOOG software suite were used to derive metallicities based on spectroscopically and photometrically estimated val...

| description | We have conducted a reanalysis of the metallicity of six red giants within NGC 3201 on the basis of a new homogeneous set of spectra with resolution ∼30,000. Iron line strengths and the MOOG software suite were used to derive metallicities based on spectroscopically and photometrically estimated values ofT
effand log g. We cannot confirm the presence of a significant spread in metallicity within the cluster greater than about 0.3 dex nor any significant correlation between metallicity and temperature, as first suggested by Gonzalez & Wallerstein. We call attention to the possibility that differences in boundary temperature for stars of the sameT
effmay lead to apparent differences in metallicity. |
