The present catalogue contains 2238 energy distribution data for 1588 objects in the spectral region 320-817nm by steps of 2.5nm. It is based on the following spectrophotometric catalogues: Kharitonov et al. (1), Alekseev et al. (the "Chilean Catalogue") (2), Willstrop (3), Glushneva et al. (the "Moscow Catalogue") (4,5,6), Burnashev's observations of stars obtained at the Crimean Astrophysical Observatory. Comparison of these catalogues and their reductions to the uniform spectrophotometric system has been carried out by Burnashev (7). The catalogue is divided in three parts: 1) Part 1 contains the data published in the catalogues by Kharitonov (1), Glushneva (4,5,6) and Willstrop(3). 2) Part 2 contains the data (and their r.m.s) of the "Chilean Catalogue" (Alekseev et al.(2)) and Burnashev's observations of some stars, obtained at the Crimean Astrophysical Observatory during 1974-1982. The observations of some variables, obtained in Chile, Are also presented. This part contains also tables of the Hydrogen continuum radiation for several temperatures (5000; 10000;15000;20000;40000;80000 K) according to Boyarchuk et al.(9), which may be useful for the analysis of the spectra of some variables. 3) Part 3 contains data of Parts 1 and 2 reduced to the uniform spectrophotometric system of the "Chilean Catalogue" in the range 320-735nm. The absolute calibration based on energy distribution of the primary standard Alpha Lyrae, according to Kharitonov (10), being the mean of the absolute calibrations of Kharitonov et al.(11), Hayes and Latham (12), Tug et al.(13).
