  The wounded nucleon and quark emission functions are extracted for different
centralities in d+Au collisions at $\sqrt{s}=200\ \text{GeV}$ using Monte Carlo
simulations and experimental data. The shape of the emission function depends
on centrality in the wounded nucleon model, whereas it is practically universal
(within uncertainties) in the wounded quark model. Predictions for
$dN_{ch}/d\eta$ distributions in p+Au and $^3$He+Au collisions are presented.
