| Abstract: | A very accurate imitation of Hipparcos and Tycho Hp, B
T, andV
T magnitudes was made using W, B, V, R magnitudes from the Tien Shan photometric catalogue. The calculated magnitudes were compared to the observed ones. It is
shown that there are systematic differences between calculated and observed magnitudes. The systematic errors are supposed
to be bound up with the sky scanning procedure on the Hipparcos satellite. Polynomials in powers of coordinates have been
proposed to take into account the systematic errors. 6558 stars have been found to be appropriate high-precision photometric
standards.
