Total local positron flux from known middle-aged pulsars within 1 kpc, except J0633+1746 and B0656+14, under the assumption that they develop a halo like J0633+1746 (top panel) or B0656+14 (bottom panel) past an age of 60 kyr, with different possible sizes for the suppressed diffusion region. For comparison, both plots also display the expected flux if all nearby pulsars develop no halo and particles released in the ISM diffuse out without experiencing any kind of strong and extended confinement around the source. By default, injection efficiencies of 100% are assumed, and several possibilities were tested for the injection index in the case of plain interstellar diffusion.
