Notes. Used denotation: ro is the nominal heliocentric distance of the star, as calculated from the known parallax, Δr(symb.) is the difference between the position of star calculated starting from the nominal heliocentric radius and velocity vectors and the position starting the calculation with these vectors calculated when the proper motion in right ascension (symb. = pmα), or proper motion in declination (symb. = pmδ), or radial velocity (symb. = Vr), or parallax (symb. = Π) is shifted about its standard deviation. Behind each value of the difference, its relative value in respect to the heliocentric distance of star in time, tapp, is given in the parentheses.
