  • Photometry of the Galactic bulge collected during the OGLE II microlensing search indicates high and nonuniform interstellar extinction toward the observed fields. I use the mean I-band magnitude and V-I color of red clump stars as a tracer of interstellar extinction toward four small regions of the Galactic bulge with highly variable reddening. A similar test is performed for the most reddened region observed in the LMC. I find that the slope of the location of red clump stars in the color… CONTINUE READING
