Mosaic of the 43 candidate AGN, selected using the IR diagnostic, which are not in the samples of MRBGD. They are ordered, from left to right and top to bottom, by increasing distance with the exception of the first three candidates, which have no known redshift/distance (see Table 2). The top images are either optical g′, r′, i′ colour images from SDSS, which are 76.8′′ on a side (except for OBJ 36, which is 153′′ on a side), or false colour images from the DSS-2-red catalogue, which are 1′ on a side (except for OBJ 6 and 8, which are 4′ on a side). The bottom images are W1, W2, W3 colour images from WISE, ~9′ on a side (except for OBJ 14, 23 and 34, which are ~4′ on a side).
