ALHAMBRA UV LF of Fig. 6 at redshift z ~ 4 and the corresponding Schechter fit (blue squares and blue line). The LF from Ono et al. (2018) is shown as white circles. The QSO LF of Akiyama et al. (2018) at z ~ 4 is plotted as red upside-down triangles. The purple line shows the best Schechter fit when this (absolute maximum) QSO contamination is subtracted from our z ~ 4 LF fit.
