From top to bottom: log [(X(Fe)/X(Fe))] as a function of velocity for DG Tau, HN Tau, DO Tau, and RW Aur. Blue and red points are the values estimated from the [Fe II]1257 and [Fe II]1644 line, respectively. Reve- rse triangles are 3σ upper limits. In each panel, the horizontal dotted line indicates the solar abundance value. The vertical line marks the rest velocity.
