+// http://www.jstatsoft.org/v05/a05/paper Table 3, page 15
+// Values of T(h,a) accurate to thirty figures were calculated using 128 bit arithmetic by
+// evaluating (9) with m = 48, the summation over k being continued until additional terms did
+// not alter the result. The resultant values Tacc(h,a) say, were validated by evaluating (8) with
+// m = 48 (i.e. 96 point Gaussian quadrature).
