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. The complete files with all
references can be downloaded and queried from

Update (08.11.2021):
The catalogue was updated with all new data available until
September 2021.
