In each panel, the red lines correspond to the 10% quantiles of the CR proton flux generated by random sources drawn in the local region. The mean value is indicated by the black curve. The flux produced by the sources that belong to our catalogue is represented in blue. The systematic errors associated to the uncertainties on the distances and ages of these objects span the grey band (standard deviation). All curves are derived with a supernova explosion rate of ν = 3century^-1. The min, med, and max propagation benchmark models are considered.
