Pseudorapidity distribution of inclusive photons measured within 2.3 $<$ $\eta_{\rm lab}$ $<$ 3.9 in p$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV compared with the charged-particle measurements  and to Hijing predictions for three centrality classes and for two centrality estimators: CL1 (top), ZNA (bottom).
