Description:
    This is the first catalogue of photometric data in the Stroemgren
    system obtained during the period October 1982 - September 1986.
    Full description can be found in ESO report SP 8.
    Since our goal is not absolute (all-sky) photometry, the observations
    should be used for differential photometry only.
    The mean values of the r.m.s. deviations of the differential
    measurements of comparison stars are around (from Table 5 of paper)
