Catalog columns

The following table lists the columns that are present in the multi-band source catalogue provided in KiDS-ESO-DR2. Measurements that are provided in each of the four filters are listed only once in the second part of the table, where in the label is either 'U', 'G', 'R', or 'I' for the filters u, g, r and i.
