1. An aerodynamic profile for a turbine vane, the aerodynamic profile defining the turbine vane when cold and in a non-coated state, the aerodynamic profile being substantially identical to a nominal profile determined by Cartesian coordinates X,Y,Zadim given in Table 1, in which the coordinate Zadim is a quotient D/H, where D is a distance of a point under consideration from a reference X,Y plane situated at a base of the nominal profile, and H is a height of said profile measured from said reference plane out to an end of the turbine vane, the measurements D and H being taken radially relative to an axial direction of a turbine, while the coordinate X is measured in the axial direction of the turbine.
