New empirical metal abundance calibrations for Washington photometry of G and K giants
An analysis of Washington photometric data of red giants in general galactic globular clusters demonstrates that the Washington abundance calibrations are affected by systematic errors due to the decrease of abundance sensitivity of (C-M) with the temperature. In this work we investigate and revise...
