Strömgren photometry in globular clusters : M 55 & M 22 ⋆
We present Strömgren CCD photometry for the two galactic globular clusters M55 (NGC 6809) and M22 (NGC 6656). We find average Strömgren metallicities of −1.71±0.04 dex for M55 and −1.62 ± 0.08 dex for M22. The determination of metal abundances in cluster giants with the Strömgren m1 index in comparison with spectroscopic data from Briley et al. (1993) and Norris & Freeman (1982, 1983) shows tha...
