 Total relative systematic uncertainty on ${\rm d}\nch$/${\rm d}\eta$ (thick black lines), as a function of pseudorapidity, compared to run-to-run fluctuations (thin red dashed lines) at $\sqrt{s} = 0.9$ TeV (top row), 2.76 TeV (second row), 7 TeV (third row) and 8 TeV (bottom row), for the INEL, NSD and INEL$>$0 event classes, as indicated.
