Gamma-ray fluxes from different CR models together with data from ARGO-YBJ (Bartoli et al. 2015) and the Tibet air shower array and muon detector array (Tibet AS+MD) (Amenomori et al. 2021) for Galactic longitudes 25° ≤l ≤ 100° and Galactic latitudes with |b|≤5°. Each colour represents a different CR model; the solid lines are with absorption, and the corresponding dotted lines without. The curves are normalised by a fit on the data by taking the absorption into account. The blue colour represents Model A, with all different CR species. The orange and red curves assume that all CR species of Model A are hydrogen or iron, respectively. The cyan curve is the emission from Model B, where the H and He CR spectra are changed with respect to Model A. The corresponding all-sky Galactic neutrino fluxes are shown in Fig. 6.
