Relative monochromatic magnitudes for 85 bright southern stars have been determined by photographic photometry at the following six wavelengths: ?? 4050, 4250, 4550, 4945, 5980, 6360. The relative energy distribution is examined as a function of spectral type. Comparisons are made with the results of other observers and it appears that while the standard of accuracy achieved for colours is good, there is evidence for a possible error of about 2 per cent in the magnitude scale.
