Photoelectric UBV observations were made with the ESO 1m telescope and the ESO photometer on 6 nights between 1970-04-01 and 1970-05-03. The observations were centered around...

We present a catalog of Chandra Source Catalog 2.0 sources cross-matched with SDSS DR15/16 counterparts. The crossmatch is performed with a Bayesian method developed by Budavari...

We present the second data release (DR2) of the XXL Survey, contextually with the appearance of a second A&A special issue dedicated to XXL. This intermediate release...

We define various types of "phantom" stars that may appear in the TESS Input Catalog (TIC), and provide examples and lists of currently known cases. We present a methodology...

The TIC is used to help identify two-minute cadence target selection for the Transiting Exoplanet Survey Satellite (TESS) mission, and to calculate physical and observational...

We present a sub-arcsecond cross-match of Gaia DR2 (Cat. I/345) against the INT Photometric H-alpha Survey of the Northern Galactic Plane Data Release 2 (IPHAS DR2, Cat. II/321)...

The K2 Mission (Howell+, 2014PASP..126..398H) uses the Kepler spacecraft to obtain high-precision photometry over ~80 day campaigns in the ecliptic plane. The Ecliptic Plane...

A catalogue of equivalent widths of H{gamma} measured by R.M. Petrie in the spectra of 1171 stars is presented. The catalogue represents a compilation of all the published and...

The catalogue of radial velocities of Galactic stars with high precision astrometric data, 2nd version (CRVAD-2), is the result of a merging of star lists from the All-Sky...

(no description available) Cone search capability for table III/250/vvds_dp (*The VVDS-DEEP Survey)

The catalogue of radial velocities of Galactic stars with high precision astrometric data (CRVAD) is the result of a merging of star lists from the General Catalog of Mean...

This catalog was initially compiled at the Abastumani Observatory, containing photographic BV magnitudes and spectral classes for about 6000 stars up to V(lim)=13.0mag in five...

This is the twelfth in a series of catalogs of MK spectral types and UBV photometry issued from Dearborn Observatory. It is based on an extensive search of literature published...

This is the fourteenth in a series of catalogs of MK spectral types and UBV photometry issued from Dearborn Observatory. It is based on an extensive search of the literature...

Spectra are presented for MK standards in the wavelength range 580-1020nm. The stars cover the normal spectral types O to M and luminosity types I, III, and V. In addition, a...

Summaries are presented of the photoelectric measurements of stellar CaII H and K line intensity made at Mount Wilson Observatory during the years 1966-1983. These results are...

A spectral survey has been made during the period 1971 to 1975 with the ESO 40cm astrograph at La Silla, equipped with its normal prism, giving an intermediate dispersion of...

This is a catalogue contains photographically determined UBVr magnitudes for more than 13000 stars at high galactic latitude. Eight pieces of information are given for each...

The catalogue contains observations of essentially all stars brighter than fifth visual magnitude north of declination -20 degrees and brighter than fourth visual magnitude...

The catalog is a compilation from the literature of all O-type stars for which spectral types, luminosity classes, and UBV photometry exist. The catalog contains 765 stars, for...
