Left-hand panel: GAMA photometric and spectroscopic redshift comparison as a function of the photometric redshift for GAMA galaxies, colour coded as function of galaxy (over-)density. The thick red central line shows the median, while the outer lines delineate the central 68 per cent of the distribution as function of z_ph. Right-hand panel: same as the left-hand panel, but for the SDSS photometric redshift estimate, extracted from the photo-redshift table in the SDSS DR7.
