WebbI tried the Horner's method from above to calculate a Bessel approximation. It works great for small numbers < 1.0. But my beta at 90 dB is 8.959. When I calculate the Bessel approximation for numbers that large then it gets pretty wild. Here are Bessel values for K = 7,8,9. 7, -4100.13715 8, 1284.70023 9, -318.22047.
