$\begin{figure} \par\includegraphics[width=18cm,clip]{12062f20.ps} \end{figure}$	Figure 15: Spitzer/IRS spectra of young stars in the Perseus cloud, in units of Jy. Gray areas correspond to 3- $\sigma$ uncertainties as estimated in Sect. 2.4. Sources are sorted by increasing Right Ascension. Red color is for SL module, orange for SH, blue for LL and dark purple for LH.
