And here is the polynomial function, if it is needed:
Linear model Poly9:
Fit14(x) = p1*x^9 + p2*x^8 + p3*x^7 + p4*x^6 +
p5*x^5 + p6*x^4 + p7*x^3 + p8*x^2 + p9*x + p10
Coefficients (with 95% confidence bounds):
p1 = 6.475e+05 (-8.204e+05, 2.115e+06)
p2 = 1.286e+06 (-1.674e+06, 4.247e+06)
p3 = 1.044e+06 (-1.389e+06, 3.477e+06)
p4 = 4.387e+05 (-6.032e+05, 1.481e+06)
p5 = 9.773e+04 (-1.478e+05, 3.433e+05)
p6 = 9523 (-2.093e+04, 3.998e+04)
p7 = -173.7 (-1854, 1507)
p8 = -95.25 (-172.1, -18.43)
p9 = 3.246 (-1.413, 7.905)
p10 = 0.004628 (-0.1033, 0.1125)
