Galactic Subsystems on the Basis of Cumulative Distribution of Space Velocities

A sample containing $4,614$ Carpet Extraction Cleaner stars with available space velocities and high-quality kinematical data from the Arihip Catalogue is formed.For the purpose of distinguishing galactic subsystems the cumulative distribution of space velocities is studied.The fractions of the three subsystems are found to be: thin disc 92%, thick disc 6% and halo 2%.

These results are verified by analysing the Dishwasher Pump elements of velocity ellipsoids and the shape and size of the galactocentric orbits of the sample stars, i.e.the planar and vertical eccentricities of the orbits.
