  The Geneva seven-colour photometric system is successfully applied to the
study of various astrophysical objects. It measures the slope of the Paschen
continuum, the Balmer discontinuity, and blocking absorption due to hydrogen or
metallic lines. One of its greatest strengths is its intrinsic homogeneity. A
new catalogue of the available measurements was generated, 30 years after the
last publication. The identifications for the individual stars were
cross-checked on the basis of the Gaia and 2MASS catalogues. The high precision
coordinates together with proper motions (if available) are included, for the
first time, in the catalogue. Special caution was exercised with binaries and
high-proper-motion stars. The catalogue includes 42 911 entries of highly
accurate photometry. The data of this catalogue can be used for various
applications, such as new calibrations of astrophysical parameters, the
standardisation of new observations, and as additional information for ongoing
and forthcoming all-sky surveys, such as the Transiting Exoplanet Survey
Satellite (TESS).
