Top:number of radio sources with identifications as a function of radio flux density and the identification method used (LR, LGZ or “expert user workflow”). The flux density distribution of all sources with identification is shown by the dot-dashed black line. Bottom: identification fraction as a function of the flux density, also split by the identification method. The identification fraction is computed based on the total number of radio sources (with or without an identification). The LGZ method dominates the identification rate above ~10mJy, with the LRmethod dominating below this. The filled regions show Poisson error estimates.
