Completeness (circles) and contamination (squares) of the J-PLUS EDR stars (left panel) and galaxies (right panel) as a function of the r-band magnitude. Sources were classified using PDF_gri = 0.5 as boundary. The coloured symbols show the estimation on individual J-PLUS EDR pointings. The white symbols are the median values of the pointings. The grey areas mark the 95% completeness and 5% contamination tolerance regions used to define the performance of our classifier.
