The KLOE Experiment at the $\phi$ factory DA$\Phi$NE, has measured the crosssection $\sigma(e^+e^-\to\pi^+\pi^-\gamma)$ using two different selectionschemes: requiring the photon emission at small polar angle and detecting thephoton at large polar angle in the calorimeter. Using a theoretical radiatorfunction we extract the pion form factor and obtain the $\pi\pi$ contributionto the anomalous magnetic moment of the muon. Results presented here come fromthe analysis of 240 pb^{-1} collected in 2002, with improved systematicuncertainty with respect to the published KLOE analysis. We also include anupdate of the previous analysis.
