V, I photometry of the bulge metal-rich globular clusters: NGC 6380 and Terzan 12 Ortolani S., Bica E., Barbuy B. <Astron. Astrophys. Suppl. Ser. 127, 471 (1998)> =1998A&AS..127..471O (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, globular ; Photometry, CCD Keywords: globular clusters: individual: NGC 6380, Terzan 12 - HR diagram Description: We present V, I photometry of the bulge globular clusters NGC 6380 and Terzan 12, using the ESO NTT telescope. For the first time colour-magnitude diagrams are obtained for these clusters, allowing us to derive reliable cluster parameters. From the colour-magnitude diagram morphology both clusters result to be metal-rich. For NGC 6380 we estimate [Fe/H]~-0.5, a reddening of E(B-V)=1.07 and a distance of d∼9.8 kpc. For Terzan 12 we obtain [Fe/H]~-0.5, E(B-V)=2.06 and d∼3.4kpc.
