The first component is a constant background $F_{NR}$, and the second one is a Breit-Wigner type amplitude associated to a quasi two body $f_0(980)$ $\\pi^{+}$ state. We show that it is possible to reproduce the observed rate for $D_s^{+} \\ra \\pi^{+}\\pi^{+}\\pi^{-}$ as well as the two other measured branching ratios for the non resonant part and the resonant $f_0\\pi^{+}$ one, with a common parameter $F_{NR}$.
