Results | The Bar and Spiral Structure Legacy Survey

http://bessel.vlbi-astrometry.org/results

Revised kinematic distance calculator. Over the past decade, we have developed and tested the techniques. Galactic Structure, Fundamental Parameters, and Noncircular Motions. With the current data, we already locate several spiral arms. Combining positions, distances, proper motions, and radial velocities yields complete three-dimensional kinematic information. By fitting the measurements to a model of the Galaxy, we estimate the distance to the Galactic center and a circular rotation speed:.
