VizieR Online Data Catalog: Properties of UCD candidates in M87/M49/M60 regions (Liu+, 2015)

The NGVS is a deep optical imaging survey in the u*, g, i, and z bands, with additional partial coverage in r, carried out with MegaCam, the 340 megapixel camera on CFHT (Boulade et al. 2003SPIE.4841...72B). The survey covers an area of Ω=104 deg² inscribed within the virial radii of the Virgo A (R₂₀₀=1.55 Mpc) and Virgo B (R₂₀₀=0.96 Mpc) subclusters (Ferrarese et al. 2012ApJS..200....4F), which are centered on M87 and M49, respectively. Beginning with the NGVS "pilot program" (see Ferrarese et al. 2012ApJS..200....4F), images were collected during six consecutive observing seasons, 2008 through 2013. Each MegaCam pointing (i.e., NGVS field) measures roughly 1°x1° on the sky. There is some overlap between fields, so that the 104 deg² survey area is covered by 117 distinct NGVS pointings.
