Comparison of photometric redshifts to spectroscopic redshifts. Top: direct comparisons of best-guess photo-z’s against GAMA DR2 spec-z’s. From left to right the panels show the BPZ photo-z’s in the DR3 multi-band catalogue, the MLPQNA photo-z’s and the ANNz2 photo-z’s. The red dashed line corresponds to zB = zspec and the contours are chosen randomly to enhance the clarity of the figures. Centre: same as the top row, but now comparing to zCOSMOS bright DR3 spec-z’s and with on the left a panel added for the BPZ photo-z’s included in the KiDS-450 shear catalogue. Bottom: normalized photo-z error δz versus r-band magnitude. The panels in the first row show the comparison to GAMA DR2 and the second row the comparison to zCOSMOS bright DR3. The order of the panels follows the order in the top and centre rows.
