The magnitudes of $v_2$ (left panel) and $v_3$ (right panel) for two different collision systems, pp and p--Pb as a function of charged-particle multiplicity at midrapidity. For pp collisions, two different $p_\mathrm{T}$ intervals are shown, $1.0< p_ gev="" and="" the="" boxes="" around="" data="" points="" represent="" estimated="" systematic="" uncertainties="" error="" bars="" corresponds="" to="" statistical="" errors.="">< /p_>
