An accuracy estimation of CCD asteroid observations contained in the Minor Planet Center Database and carried out in the years 1999 - 2006 is realized. About 20 millions individual positions of the Numbered and Unnumbered Minor Planets were tested by means of calculations of (O-C) residuals to derive "mean error of a single observation" for more than 400

... The kinematics, structure, and stellar population properties in the centers of two early-type spiral galaxies of the Leo Triplet, NGC 3627 and NGC 3623, are studied by means of integral-field spectroscopy. ... In the center of NGC 3627 we observe noticeable gas radial motions, and the stars and the ionized gas in the center of NGC 3623 demonstrate more or less stable rotation. ... In this work we consider two nearby early-type spiral galaxies belonging to the famous Leo Triplet, NGC 3623 and NGC...
