On Perihelion Concentration of Long-period Comets II. Correct Access

The problem of (non)random distribution of points on sphere and in space is investigated. The procedure for obtaining preferred direction (and plane) for points on the sphere (in the sky) and in the space is discussed. At present, directions of perihelia of the observed long-period comets cannot be considered to be distributed uniformly in the sky (contrary of the statement made by Neslu\v{s}an 1996). The action of galactic disk should increase the concentration in the zone of galactic latitude $b \approx 0^{\circ}$, unless the observational selection effects play an important role.
