Abstract
It seems by now well-established that in the central kpc the Galaxy is not axisymmetric (Gerhard 1995, Dwek 1995). The kinematics of many different tracers, as well as the distribution of sources on the sky, all point to an elongated distribution of matter and of the potential, with the long axis of the distortion pointing somewhere in the first Galactic quadrant. It is therefore tempting to reconsider our data concerning this part of the Galaxy in terms of ‘the’ Bar. But to what extent should we (or is it useful to) distinguish between the bar and the stellar bulge of old?
