Description:
This catalogue is a supplement of the Ultraviolet Bright Star
Spectrophotometric Catalogue (=III/39A). It contains observations
carried out by the S2/68 Ultraviolet Sky Survey Telescope (UVSST)
aboard the ESRO satellite TD-1. The data presented in this supplement
were obtained during the second and third observation periods, which
lasted from 19 February 1973 to 30 September 1973 and from 16 February
to 6 May 1974. The S2/68 experiment has been described by Boksenberg
et al. (=1973MNRAS.163..291B 1973MNRAS.163..291B)
Owing to the optical scanning mode, most of the stars observed during
the first observational period, the spectra of which are included in
the "Ultraviolet Bright-Star Spectrophotometric Catalogue", were
seen again by the telescope. This supplement, however, has been
limited to the spectra of stars that were not observed during the
first period. The data reduction and selection criteria are identical
to those underlying the main Catalogue and hence the data presented in
the Supplement are directly comparable with those in the main
Catalogue.
The Supplement contains data for 435 stars. For a statistical summary
of the observed stars, see the tables I and II in the published version
of the Supplement. The spectrum scanning itself was achieved by the
movement of a star image across the wide entrance slot of the
spectrophotometer, which caused the corresponding spectrum image to
pass over the three exit slits in the direction of dispersion. The
motion of the primary image during each detector integration interval
(0.148 s) was equivalent to 19.4 A, depending on the channel. The
wavelength range covered was 1350 - 2550 A. The passband of the
photometer channel, defined by a glass transmission filter and the
photocathode tube response, was centered at 2740 A and had a full
width at half height of 310 A.

Historical Notes:
* The catalogue was provided to CDS by G.I. Thompson in 1979.
* A CD-ROM version with most of the enclosed description section
was created in October 1991 at ADC on the
"Selected Astronomical Catalogs" Vol. 1 , directory
/spectro/uvbssupp
* 24-Oct-1995: the catalog was reformatted at CDS (Francois Ochsenbein);
the following modifications were performed:
=> the positions were added from HD (=III/135) catalogue
=> there were initially 132 columns for lambda (the wavelength),
132 columns for the corresponding Fluxes and 132 columns for
the mean errors. The lambda columns were removed; the
corresponding fluxes and errors were moved to fixed positions.
=> unknown values, originally indicated by zero fluxes and " -" in
the mean errors, have been blanked.
