VizieR Online Data Catalog: Planetary nebulae in MACHO Galactic Bulge (Lutz+, 2010)
Abstract
The MACHO project (Alcock et al., 1997ApJ...486..697A) comprises observations taken over an 8-yr period of the Large and Small Magellanic Clouds and the bulge of the Milky Way. Our sample of PNCS is drawn from both the MACHO variable star catalogs (Alcock et al., 2003, Cat. II/247) and the full database of detected sources. Sources from the full MACHO database of millions of objects were selected for the MGB Variable Star Catalog if the central 80% of points in the object's light curve failed to fit a constant magnitude in a chi-square test. This criterion resulted in 521007 candidate variables in the Galactic bulge (http://wwwmacho.anu.edu.au/ )
