Galaxy and Mass Assembly (GAMA): maximum-likelihood determination of the luminosity function and its evolution

We describe modifications to the joint stepwise maximum likelihood method of (2011) in order to simultaneously fit the GAMA-II galaxy luminosity (LF), corrected for radial density variations, and its evolution with. The whole sample is reasonably well-fit with luminosity (Qe) and (Pe) evolution parameters Qe, Pe = 1. 0, 1. 0 but with significant characterized by Qe = 1. 4 - 0. 4Pe. Blue galaxies exhibit larger density evolution than red galaxies, as expected. We present the-corrected r-band LF for the whole sample and for blue and red-samples, using both Petrosian and Sersic magnitudes. Petrosian magnitudes a substantial fraction of the flux of de Vaucouleurs profile galaxies: the LF is substantially higher than the Petrosian LF at the bright end.
