Supplement to the ultraviolet bright-star spectrophotometric catalogue : a compilation of absolute spectrophotometric data obtained with the Sky Survay Telescope (S2/68) on the European Astronomical Satellite TD-1

This supplement to the catalog (ESA SR-27, November 1976) contains data obtained during the second and third observation periods, which lasted from 19 February 1973 to 30 September 1973 and from 16 February 1974 to 6 May 1974. Although most of the stars listed in the catalog were seen again during the second and third observation periods, the spectra presented in this supplement are those of stars that were not seen during the first period. The data reduction and selection criteria remain unchanged, so the data presented in the supplement are directly comparable with those in the main catalog.
