Abstract
The circular velocity of the thick disc is investigated using data in the 5 dimensional space (V, B‐V, U‐B, μl, μb) in a direction at intermediate latitude. We show that using a discriminant analysis we are able to distinguish the thick disc from the disc and the halo and that these data constrain the asymmetric drift of this population. It is found to be 80±20 km/s at a 2 sigmas level.
