Reddening Distribution across the Center of the Globular Cluster ω Centauri
We present new medium-band uvby Strömgren and broadband VI photometry for the central regions of the globular cluster ω Cen. From this photometry we have obtained differential reddening estimates relative to two other globular clusters (M13 and NGC 288) using a metallicity-independent, reddening-free temperature index, [c]≡(u-v)-(v-b)-0.2(b-y), for
