Stroemgren photometry of Dwarf Novae
A sample of 26 dwarf novae was observed in the Stroemgren photometric system. The observations were performed on 3 different seasons in 1986 January, February and July, with a... -
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... -
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... -

The Catalogue of Individual UBV and uvby-beta Observations of Stars in the Region of the Orion OB 1 Association presents individual UBV observations of 106 stars in the vicinity... -
uvby-beta Photometry for Bright O-G0 Southern Stars
The catalog includes for each star as described in the title, the CDS number, HR number, V magnitude, (b-y) color index, m1, c1, beta, mean errors, sum of remarks. The rms... -
uvby-beta Catalogue
This catalogue is an updated version of the one published in 1990 (Hauck and Mermilliod, 1990) and contains data for more than 63,300 stars in the Galaxy and Magellanic Clouds.... -
Palomar-Green catalog UV-excess stellar objects
The Palomar-Green Catalogue of UV-excess stellar objects provides positions accurate to about 8arcsec in each coordinate, photographic B-magnitudes accurate to 0.29mag, spectral... -

Observations of the Ap Star HR 1217 from 1980-86
This file contains magnitudes from nearly 50,000 40 second observations of the rapidly oscillating Ap star HR 1217 obtained during nearly 600 hours of observation at various... -
Visual Double Stars with Early-Type Primaries. IV
Astrophysical parameters (MK class, colour excess, absolute magnitude, distance, effective temperature, mass and age) are derived from calibrations of the uvbybeta indices for... -
uvby{beta} photometry of NGC 663
We present CCD uvby{beta} photometry for stars in the central area of the young open cluster NGC 663. We find that the reddening is highly variable, with values ranging from... -
uvby photometry of AB Cas
Table 1 contents 1313 simultaneous measurements collected in each of the four uvby colours of the Stromgren photometric system for the semi-detached Algol-type eclipsing binary... -
G and K dwarfs UBV(RI)c and ubvy photometry
K dwarfs have lifetimes older than the present age of the Galactic disc, and are thus ideal stars for investigating the chemical evolution of the disc. We have developed several... -
Ca,by photometry in globular clusters. I. M22
We investigate the multiple stellar populations in one of the peculiar globular clusters (GCs), M22, using new ground-based wide-field Ca by and Hubble Space Telescope... -
byH{alpha} photometry in open clusters
Be stars are a class of rapidly rotating B stars with circumstellar disks that cause Balmer and other line emission. There are three possible reasons for the rapid rotation of...
