Redshift versus Petrosian r-band absolute magnitude (M_r) for GAMA sources with reliable redshift and stellar mass estimates (gray dots). The four color boxes correspond to each of the stellar-mass-selected samples: 0.07 <z< 0.1 (blue), 0.1 <z< 0.15 (green), 0.17 <z< 0.2 (pink), and 0.2<z<0.3 (red), and are representative between −23 <M_r< − 18.4, −23 <M_r< − 19.2, −23 <M_r< − 20.4, and −23 <M_r< − 21, respectively. The dashed and dotted lines are the M_r limits corresponding to the apparent magnitude limits of the SDSS (m_r> 14.5 for the bright limit and m_r< 17.7). The black solid line indicates M_r limits corresponding to the apparent magnitude limits of GAMA (m_r< 19.8).
