Comparison of KiDS r-band GAaP photometry to Gaia DR1 G-band and SDSS DR9 r-band photometry. Stars with dereddened gi colours, based on colour-calibrated KiDS GAaP data (x-axis), between 0.2 and 1.5 are selected to iteratively derive the median photometric offsets (rG)0 (left sequence) and (rrSDSS) (right sequence). The latter sequence of data points is shifted by 1.6 mag in (gi)0 for clarity. The red and green outlines show the regions encompassing the data points used in the final iteration of each fit.

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.
