We look at a scaled double derivative of the static quark-antiquark potential which becomes the Lüscher term asymptotically. Comparing our simulation data with effective string models, we find strong evidence for a nambu-Goto type string. We comment on scales where the flux tube starts being well described by effective strings. In the intermediate regions, we find an empirical expression which smoothly interpolates the data.
