Interstellar extinction towards the inner Galactic Bulge
Abstract
DENIS observations in the J (1.25 mu m) and KS (2.15 mu m) bands together with isochrones calculated for the RGB and AGB phase are used to draw an extinction map of the inner Galactic Bulge. The uncertainty in this method is mainly limited by the optical depth of the Bulge itself. A comparison with fields of known extinction shows a very good agreement. We present an extinction map for the inner Galactic Bulge (~ 20 deg(2) ) Based on observations collected at the European Southern Observatory, La Silla Chile
