Beginning of ReadMe : J/PASP/122/524 Planetary nebulae in MACHO Galactic Bulge (Lutz+, 2010) ================================================================================ Planetary nebula central stars and symbiotic stars in the MACHO Galactic Bulge database. Lutz J., Fraser O., McKeever J., Tugaga D. <Publ. Astron. Soc. Pac., 122, 524-535 (2010)> =2010PASP..122..524L ================================================================================ ADC_Keywords: Planetary nebulae ; Stars, distances ; Photometry, Cousins Abstract: We have examined central stars of planetary nebulae and symbiotic stars found in the MACHO Galactic bulge database to look for variability. We found four central stars of planetary nebulae and eight symbiotic stars that show variability. We examine the variability and the nature of these objects in detail, as well as reporting on the objects that we did not find to be variable. Description: 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/ )
