Raw differential number counts of red sources from several studies. HeViCS number counts are presented with black stars, connected with a full, black line. Counts from Asboth et al. (2016) are indicated with black circles and connected with dotted lines, whilst observational findings of Dowell et al. (2014) are presented with dashed black lines. Filled points have Poisson 1σ error-bars added, and for the brightest flux bins with low statistics of sources, we plot the upper 95% confidence levels.
