J/A+A/317/448       BVRHalpha photometry of NGC 1818 (Grebel 1997)

Be star surveys with CCD photometry. II. NGC 1818 and its neighbouring cluster in the LMC. Grebel E.K. <Astron. Astrophys. 317, 448 (1997)> =1997A&A...317..448G (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, globular ; Photometry, CCD Keywords: galaxies: Magellanic Clouds - clusters: globular: NGC 1818 (LMC) - galaxies: star clusters - stars: emission-line, Be - stars: fundamental parameters Description: We present B,V,R,Halpha CCD photometry and astrometry of Be stars in NGC 1818, its small neighbouring cluster NGC 1818B, and the surrounding field down to V = 18 mag. Our Be star identifiers conform to IAU specifications. For a description of the UBVRI and Halpha systems, see e.g. GCPD/08 and GCPD/55 File Summary:
