Washington photometry of globular cluster giants: the most metal-poor clusters
We present photometry on the Washington system for 125 stars in 10 of the most metal-poor Galactic globular clusters. Luminosity class, temperature, and metal abundance are derived for each star. A new temperature calibration is presented, based on recent model atmosphere calculations by Bell &...
