Luminosity functions and their respective fits for the 4 different redshift bins considered in this study. The red and grey squares represent the points derived in this work, where the grey squares are considered incomplete and are not used in the different fits. The literature points used to constrain the bright end of the LFs are shown as lightly coloured diamonds. The black points represent the results obtained by Cassata et al. (2011), which were not used for the fits. The purple squares represent the points derived using the V_max method in D17 and are only shown for comparison. The best Schechter fits are shown as a solid line and the 68% and 95% confidence areas as dark red coloured regions, respectively.
