Probable new halo stars toward L = 360 deg, B = +30 deg
The Stock objective-prism radial-velocity survey catalog has beensearched for probable halo giants at intermediate Galactic longitude. Atotal of 83 objects were found. The sample yielded a velocity dispersionof 98 + or - 8 km/sec and a frequency of 0.15 halo giants brighter thanm(pg) = 11.5/sq deg.

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.
