The current consensus regarding the absolute calibrations of the spectra of α Lyr and some subdwarfs has led the authors to revise the calibration of the Geneva photometric system's passbands. The alterations made to the earlier version by Rufener and Maeder (1971) are smaller than ±5%. The new response functions are presented in tabular form for an equiphotonic flux. An absolute spectrophotometric adjustment allows to obtain for each entry of the Geneva catalogue (now ≡29400 stars) a corresponding spectrophotometric description in SI units. The coherence of the Geneva catalogue with several sets of absolute spectrophotometric data is examined.
