J/A+A/580/A23  Stroemgren-Crawford uvbyβ photometry catalog (Paunzen, 2015)

A new catalogue of Stroemgren-Crawford uvbyβ photometry. Paunzen E. <Astron. Astrophys. 580, A23 (2015)> =2015A&A...580A..23P
ADC_Keywords: Positional data ; Photometry, uvby, beta ; Photometry, CCD Keywords: catalogs - techniques: photometric Abstract: The uvbyβ photometric system is widely used for the study of various Galactic and extragalactic objects. It measures the colour due to temperature differences, the Balmer discontinuity, and blanketing absorption due to metals. A new all-sky catalogue of all available uvbyβ measurements from the literature was generated. The data for the individual stars were cross-checked on the basis of the Tycho-2 catalogue. Description: This catalogue includes very precise celestial coordinates, but is magnitude and spatial resolution limited. However, the loss of objects is only marginal and is compensated for by the gain of homogeneity. In total, 298639 measurements of 60668 stars were used to derive unweighted mean indices and their errors. Photoelectric and CCD observations were treated in the same way. For the new catalogue, the literature through the end of 2014 was searched for photoelectric and CCD uvbybeta measurements The contents will be updated regularly.
