1. A turbine vane for a gas turbine engine comprising:

  • inner and outer platforms joined by a radially extending airfoil, the airfoil including leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface; and

    wherein the inner and outer platforms respectively include inner and outer sets of film cooling holes, wherein one of the inner and outer sets of film cooling holes are formed in substantial conformance with platform cooling hole locations described by one of the sets of Cartesian coordinates set forth in Tables 1 and 2, the Cartesian coordinates provided by an axial coordinate, a circumferential coordinate, and a radial coordinate, relative to a zero-coordinate, and the cooling holes with Cartesian coordinates in Tables 1 and 2 have a diametrical surface tolerance relative to the specified coordinates of 0.200 inches (5.08 mm).
