Fig. A.1


Left panel: predicted abundances for several nitrogen bearing species in L1498 for our best-fit model with an updated chemistry network (see text). The solid lines correspond to gas-phase abundances, and the dashed lines to ice abundances. Right panel: same as in the left panel, but now assuming that most of nitrogen is initially in form of NH3 ices, with an abundance of 8.5% relative to H2O ices.
