Radial velocities of faint stars from objective prism plates
A simple method by which the approximate radial velocity of a star maybe obtained from objective prism plates is described in detail. Themethod has been used to derive the velocities of 41 faint stars, most ofwhich have metal-weak spectra and are shown to be high-velocity objects.It is shown that this method may be generalized so that the radialvelocities for all measurable stars on an objective prism plate can beobtained.
