Scientific paper
The catalog is a compilation of uvby and H-beta photoelectric photometric data published in the literature through the end of 1988. It supersedes an earlier edition by the same compilers (1985A&AS...60...61H). All individual observations are given in one file, while a separate file contains a single set of homogeneous means for each object. Other files give the complete set of bibliographical references and a definition of the Geneva coded numbering system used to identify the stars. The compilation includes 69190 observations of 44896 stars. The homogeneous means were computed using the method of Lindemann and Hauck (1973A&AS...11..119L). This method refers each source back to the standard system and compares all stars in common. Weights are computed based on this comparison, then used when the final means are computed for each star. In general, these means will be the best values for each object but may not be suitable for all applications, especially when variability is suspected. The data in the observations file include coded number (identifier), double and variable codes, V magnitude, uvby, beta indices and numbers of observations, and reference code. The homogeneous means file contains only the object identifier and the homogeneous indices of the uvby, beta system. (No V magnitudes are included in the means file.) (3 data files).
