1999AJ....118..381L - Astron. J., 118, 381-389 (1999/July-0)
A major star formation region in the receding tip of the stellar galactic bar. II. Supplementary information and evidence that the bar is not the same structure as the triaxial bulge previously reported.

Abstract (from CDS):
Equivalent spectroscopic analysis should also be performed at l=-22°, the candidate position for the other tip of the bar. The space localization of one and a fortiori of both ends of the bar allows us to infer its orientation. If the second region is also confirmed to be a powerful star formation region this would imply a position angle for the bar of about 75° with respect to the Sun-Galactic center line. This geometry is indeed compatible with the range of distances that we have obtained for the star-forming region at l=27° from spectroscopic parallaxes. However, the angle is different from that given by other authors for the bar, and this, we think, is because they refer to the triaxial bulge and not to the bar as detected here.
