Notes. (α)In each modified model, only one parameter at a time is changed with respect to the reference model. (b)Shell full opening angle at z = 800 au. We obtain α800 = 88° for the reference model. (c)Full shell width at z = 800 au. We obtain W800 = 2.3 × 1016cm for the reference model. (d)Full shell width at z = 12700 au (top of the grid). We obtain W12700 = 7.6 × 1016cm for the reference model. (e)High jet density case, yielding a one-sided mass-flux 
M⊙/yr for the reference values of θj and Rj.
