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)
