Abstract At Mount Stromlo Observatory and its Mount Bingar field station, spectral-energy distributions have been measured for a number of southern stars by comparing them with appropriate northern spectrophotometric-standard stars. The spectral traces, obtained with a scanner designed by Ljller and equipped with a P21 photomultiplier tube, cover the wavelength range from 3400 to 5870 A with a band pass of 10 A. Since a Lyrae is not a satisfactory reference from the latitude of the Australian observatories, Oke's program star Ceti is chosen as the fundamental energy-distribution standard, and all observations are ultimately referred to it. Most of the data are handled by a spectrophotometric network, analogous to a triangulation network, the energy distributions, which are expressed as being smoothed at the last step. The accidental errors in the energy distributions amount to about +1 per cent in the wavelength range A; they are about +2 per cent for X < 3600 A and +5 per cent for X > 5500 A. Comparisons with the results obtained by Bahner, Code, and Oke for stars common to our list show generally good agreement except in the ultraviolet of a Leonis and 58 Aquilae.
