Description:
    Table 2 contains 408 simultaneous measurements collected in each of
    the four uvby colours of the Stromgren photometric system for the W
    UMa system HD 163151. The data are magnitude differences
    (Du, Dv, Db, Dy, D(b-y), Dm1, Dc1) of the variable star minus
    comparison star in the standard system versus Heliocentric Julian Day.
    Tables 3, 4 and 5 are the same, but for H{beta} (65 points), Johnson B
    data (212 points) and Johnson V data (355 points). The comparison star
    is HD 166095. The origin in time is the Julian Day 2449858. The
    observations were carried out (by E. Rodriguez, A. Claret, J.M.
    Garcia, F.M. Zerbi, R. Garrido, S. Martin, C. Akan, K. Luedeke, V.
    Keskin, C. Ibanoglu, S. Evren, Z. Tunca, R. Pekunlu, M. Paparo, J.
    Nuspl, K. Krisciunas and S.Y. Jiang) in 1995 during the course of a
    multisite campaign. The following telescopes were used: 90cm telescope
    of the Sierra Nevada Observatory, Spain (uvby-H{beta} photometry);
    50cm telescope at the Ege University Observatory, Turkey (BV-uvby);
    50cm telescope at Piszkesteto mountain station, Konkoly Observatory,
    Hungary (BV); 50cm telescope at the Merate Observatory, Italy (V); 30cm
    telescope at Albuquerque, New Mexico, USA (V) and 15cm telescope at
    Mauna Kea, Hawaii, USA (V).
