Notes. The B, R, I and z-band data have already been described in a previous paper (Kong et al. 2006). The XMM and Chandra data have also been described in other papers (Brusa et al. 2005; Campisi et al. 2009). The raw IRAC and MIPS data were taken from the archive and reduced using MOPEX and custom scripts.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
