Calibration of Strömgren uvby-Hβ photometry for late-type stars – a model atmosphere approach

Free Access

Table 6:

Derived effective temperatures from empirical calibrations of photometry ((b-y) and (v-y)), and spectroscopy (Korn et al. 2007), as well as our theoretical calibration, for groups of stars in the metal-poor cluster NGC 6397. The temperatures are mean values for a number of stars/models in each group.
