VizieR Online Data Catalog: Wide metal-poor binaries BVRI photometry (Zapatero Osorio+, 2004)
Abstract
Observing dates, differential photometry and astrometry (rho and position angle) of companion candidates around 473 nearby, low-metallicity G- to M-type stars are provided in the Table. The target stars were mainly taken from the Carney-Latham surveys. Also provided are exposure times, the FWHM of the CCD images, and the telescope used for collecting the observations. The last column contains a flag indicating whether the candidate is a confirmed physical companion.
