Erratum: Detection of a $\gamma$-ray halo around Geminga with the Fermi-LAT data and implications for the positron flux [Phys. Rev. D 100, 123015 (2019)]

Figure 1

$e^{+}$ flux at Earth from Geminga. Blue (purple) curves are for K15 (G15) propagation models for $r_b=100\mathrm{pc}$ and ${\gamma }_e=1.9$. The cyan band embeds the differences in the results considering these two propagation parameters and the choice of ${\gamma }_e$, from ${\gamma }_e=1.8$ (red and orange dash-dotted lines) to ${\gamma }_e=2$ (black and gray solid lines). We also report with a green line (solid for K15 and dashed for G15) in the top left panel the case with $r_b=30\mathrm{pc}$, ${\gamma }_e=2.0$ and with $\eta$ found from a fit to the HAWC surface brightness.
