Abstract:
DENIS observations in the J(1.25{mu}m) and K_S_(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^)
Description:
This table provides the Av values for the inner galactic Bulge with a
resolution of 2'. The Av values were derived assuming
Av:Aj:Ak=1:0.256:0.089 (Glass, 1999, Handbook of Infrared Astronomy,
Cambridge, Univ. Press). This table provides the interstellar
extinction for a longitude range between -8 and +8 degrees and for
-1.5<b<1.5 degrees.
