My remarks concern the kinematics of a-type RR Lyrae variables with large ∆s(≥5), supposedly halo members, which have relatively well determined proper motions (μ) and radial velocities (ϱ) as well as accurate photoelectric photometry (m). The number of variables fulfilling these criteria is about 60. Using procedures which need not be discussed in detail here, it is possible to determine the statistical kinematic properties of these stars - that is, their solar motion (υ) and velocity dispersion (σ) - in two different ways:
