Scientific paper

Whereas the 1964 IAU standard values of the constants R0 = 10 kpc, θ0 = 250 km s-1, A = 15 km s-1kpc-1, and B = -10 km s-1kpc-1, differ from those currently considered best, the errors of current determinations are still rather large. Although the means of recent determinations lead to a fairly consistent set of values for the four main constants, the agreement may be largely coincidental. However, a case can be made for agreeing on the pair of standard values R0 = 8.5 kpc and θ0 = 220 km s-1. On the basis of this review these were adopted by resolution of IAU Commission 33 on 1985 November 21 at Delhi.
