					Q at natural period of differential oscillation of the test cylinders with respect  to one another
			Relative displacements (X,Y) between the centers of mass of the test cylinders at zero spin rate, 8 sec natural periods of differential oscillations. The amplitudes of these oscillations are slowly decreasing with time; data sets taken at subsequent times -under no changes in the system- yield Q@1590. Residual air pressure during this measurement is of 2×10-5 mbar.
