NGVS observing status as of 2011 September, i.e., at the end of year three. Long and short exposures are shown in the top and bottom rows, respectively, while the filters are ordered from u* to z from left to right. Fields for which observations have been completed are indicated by colored filled squares, while only partial data have been obtained for dashed fields. Fields shown as empty squares will be observed in 2012 or beyond. The orange outline indicates the virial radii of Virgo's A and B subclusters, while the crosses mark the location of M87 to the north, M49 to the south, and M60 to the east.
