UBVRIJKLMNH Photoelectric Catalogue
The catalog contains the results from star brightness measures in the first ten (UBVRIJKLMN) broad wavelength bands (Johnson 1965) and the additional bandpass H (Johnson et al.... -
uvby-Beta Phot 398 Members of Visual Multiple Systems
The catalogue contains mainly two types of visual double stars: Evolved stars with main sequence companions; and systems, for which the IDS gives photometric and spectroscopic... -
Homogeneous RI magnitudes in Kron system
This catalogue (file "mean") contains homogeneous data in the photoelectric photometric system of Kron and Smith. The R magnitude and the R-I colour index have been collected... -
UBV Photometry of Bright Stars
The data presented in this catalogue are the results of multicolor photometric observations of stars listed in the Bright Star Catalog. Observations were made on the 21-in,... -
Photometric Standard Stars
The non-variable stars brighter than 5.0 mag in the equatorial zone between declinations +10{deg} and -10{deg} were adopted by IAU Commission 25 in 1970 as primary standards for... -
A Reference List for the UBV System
This catalog is a file of 13422 records giving for each star, an identification, V, B-V, and U-B. Care was taken to place all measurements on the Johnson UBV system by... -
Strong cyanogen stars
A cyanogen index for late-type giants, insensitive to surface gravity but sensitive to metallicity, is presented in the David Dunlap Observatory (DDO) photometric system.... -
Photometry of strong CN stars
A group of 185 late G and K giants, selected from the US Naval Observatory Catalog of Photoelectric Observations (Cat. II/4) because they had Ultraviolet deficiences, were... -
K-Line photometry of stars in Population I clusters
Photoelectric photometry of the K-line of calcium has been performed for the A stars of five open clusters (Hyades, Pleiades, IC 2391, IC 2602, and NGC 6475) and one association... -
K-line photometry of Southern A stars
The photoelectric measurements of the strength of the Calcium K-line has been extended by 223 stars of predominantly southern or equatorial declinations which are well... -
K-Line Photometry of A Stars
A narrow-band spectrometer, compensated for seeing and transparency variations, has been constructed and used to measure the strength of the calcium K-line (3933.68{AA}) in 146... -
420nm CN and G bands in G8-K5 spectra
Measurements of the {lambda}4200{AA} CN band are presented for 712 late-type stars. G band data are also included for 212 of these stars. Mean errors of absolute magnitudes... -
Hydrogen-Line Absorption in Early-Type Stars
Photoelectric determinations of H-{gamma} absorption line intensity have been made of stars in selected clusters and associations as well as in the general galactic field.... -
Euclid final merged catalog. Q1 data release
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown.... -
VPHAS+ DR3 survey
The primary goal of the VST Photometric H{alpha} Survey of the Southern Galactic Plane and Bulge (VPHAS+) is to collect single-epoch ugri broad-band and Ha narrow-band... -
VLT Survey Telescope ATLAS DR4
The VLT Survey Telescope ATLAS survey is an optical ugriz survey aiming to cover ~4700deg^2^ of the southern sky to similar depths as the Sloan Digital Sky Survey (SDSS). From... -
SkyMapper Southern Sky Survey. DR4
We present the fourth data release (DR4) of the SkyMapper Southern Survey (SMSS), the last major step in our hemispheric survey with six optical filters: u, v, g, r, i, z. SMSS... -
Spitzer Data Fusion main catalogue
We present the Spitzer Data Fusion, a database incorporating far-ultraviolet to far-infrared flux measurements as well as photometric and spectroscopic redshifts for 4.4 million... -
RGB photometric calibration of 213 million Gaia stars
Recent works have made strong efforts to produce standardised photometry in RGB bands. For this purpose, we carefully defined the transmissivity curves of RGB bands and defined... -
The Dark Energy Survey (DES): Data Release 2
We present the second public data release of the Dark Energy Survey, DES DR2, based on optical/near-infrared imaging by the Dark Energy Camera mounted on the 4m Blanco telescope...
