The position angle of the Galactic bulge
Abstract
We present a study of the structure of the Galactic Bulge in the region −6° < b < 3°,−17° < l < 17° using 2MASS archive data. More than 100 fields are used. We make use of the red clump method to derive the distance of the Bulge in the studied regions. We derive a position angle of the Galactic Bulge going from 42° ± 11 to 35° ± 10 depending on the adopted bulge mass distribution.
