- Title:
- Intrinsic Colours of Stars in the Ultraviolet
- Short Name:
- II/91

- Publisher:
- CDS
- Description:
- The catalog contains intrinsic ultraviolet colors for normal stars between O6.5V and K3III. These have been derived from the absolute ultraviolet fluxes obtained by the S2/68 Ultraviolet Sky Survey Telescope aboard the ESRO TD1 satellite, corrected to the standard calibration of Bohlin et al. (1981) for the star eta UMa. The catalog contains 671 records, one for each MK spectral type and luminosity class between O6.5Ia and K3V. Each record consists of twenty-five broad- and narrow-band colors in the form (m(lambda) - V)(0) covering the wavelength range 1400A to 2740A. Complementary data including (B-V)(0), (U-B)(0), and absolute visual magnitude, M(v), are also given for each type. The intrinsic ultraviolet colours cover three groups of passbands: (1) Four broadband fluxes (width 330 Angstroms) centred on 1565A, 1965A, 2365A and 2740A. (2) Nine narrowband fluxes (width 110 Angstroms) centred on 1455A, 1565A, 1675A, 1855A, 1965A, 2075A, 2255A, 2365A, 2465A (3) Twelve narrowband fluxes (width 100 Angstroms) centred on 1400A, 1500A, 1600A, 1700A, 1800A, 1900A, 2000A, 2100A, 2200A, 2300A, 2400A, 2500A

- Title:
- UV Bright Star Spectrophotometric Catalog
- Short Name:
- III/39A
- Date:

- Publisher:
- CDS
- Description:
- This catalogue contains observations carried out by the S2/68 Ultraviolet Sky Survey Telescope (UVSST) aboard the ESRO Satellite TD-1, which measured the absolute ultraviolet flux distribution between 2740A (274nm) and 1350A (135nm). The data presented in this catalogue were obtained during the first observation period, which lasted from 19 March 1972 to 31 October 1972, and contains the brightest objects, for which the signal is good enough to give valuable spectrophotometric information. The Faint Star Catalogue, which contains the photometric data of the stars up to the limit of detectability of the instrument, is known as the "Catalogue of Ultraviolet Fluxes", by Thompson et al. (catalog <II/59>) The S2/68 experiment has been described by Boksenberg et al. (=1973MNRAS.163..291B) and the absolute calibration by Humphries et al. (=1976A&A....49..389H).

- UV Bright-Star Spectrophotometric Supplement

- 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) 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.
