  • We present the reddening [E(V - I)] and extinction maps in the V band (A V ) and the I band (A I ) for 48 Optical Gravitational Lensing Experiment II (OGLE-II) Galactic bulge (GB) fields, covering a range of -11° < l < 11°, with the total area close to 11 deg 2 . These measurements are based on two-band photometry of red clump giant (RCG) stars in OGLE-II VI maps of the GB. We confirm the anomalous value of the ratio of total to selective extinction R VI ≡ A V /E(V - I) = 1.9-2.1, depending on… CONTINUE READING
