VizieR Online Data Catalog: Globular Clusters of NGC 4278 in SLUGGS (Usher+, 2013)

As part of the SLUGGS (sluggs.swin.edu.au) survey of globular clusters (GCs) around early-type galaxies we have used archival HST ACS and Subaru Suprime-Cam imaging to study the GC system of the giant elliptical galaxy NGC 4278. We used magnitude, colour and size cuts to select candidate GCs from the ACS imaging and used magnitude and colour-colour cuts to select candidates from from the Suprime-Cam imaging. We study the spatial, colour and size distributions of the candidates. We also obtained a number of spectra of GC candidates with DEIMOS on Keck adding a handful of confirmed GCs and ultra compact dwarfs to the sample of Pota et al. (2013MNRAS.428..389P, Cat. J/MNRAS/428/389). Metallicities were measured using the technique of Usher et al. (2012MNRAS.426.1475U, Cat. J/MNRAS/426/1475).
