Appendix A: 2-Dimensional abundances including grain surface chemistry

$\begin{figure}\par\includegraphics[trim =0 0 0 0cm,width= 8.5cm]{1471fi21} \end{figure}$	Figure A.1: Distribution of HCO⁺ throughout the core at four different times during the simulation for Model S. The black contour shows the outline of the disk. The disk is defined as the region where $\sqrt {v_z^2 + v_R^2} \leq v_\phi$ , with $v_\phi$ the rotational velocity.
