J/A+A/380/478 BVI photometry in NGC 6101 (Marconi+, 2001) ================================================================================ Mass segregation of different populations inside the cluster NGC 6101. Marconi G., Andreuzzi G., Pulone L., Cassisi S., Testa V., Buonanno R. =2001A&A...380..478M ================================================================================ ADC_Keywords: Clusters, globular ; Photometry, CCD Keywords: globular clusters: individual (NGC 6101) - stars: fundamental parameters - Hertzsprung-Russell diagram - stars: abundances - stars: horizontal branch Description: We used HST-WFPC2 and the 1.54 Danish ESO-telescope at La Silla (Chile) to obtain photometry for stars located within 200 arcsec from the center of the cluster NGC 6101. HST-WFPC2 data for 1 field centered on the cluster, have been collected during HST-cycle 6. The resulting V, V-I photometry reach a limiting magnitude of V~25.5. Ground observations have been collected on July 1995. The resulting photometry containing the stars simultaneously detected in the V, B and I filters, is characterized by a limiting magnitude of V~22.5.
