An investigation of the structure of non-uniformities of interstellar absorption using photometry of globular clusters
Abstract:Charge-coupled device photometric investigations of the central regions of the globular clusters NGC 4372 (r < 4′) and NGC 6266 (0.5′ < r < 2′) were used to obtain detailed maps of the distribution of differential reddening. In both clusters the reddening is non-uniform on angular scales less than 1′ and varies by magnitudes of 0.15 and 0.20 within the investigated fields of NGC 4372 and NGC 6266 respectively. For these clusters the average E(B − V) values of magnitudes 0.34 and 0.43 are smaller than those found previously.
