description
Everett polynomial coefficients for 1-WAY frequency prediction. To calculate predicted frequency (Fp) at time t use the following equations: Fp(t) = (1-p)*f0 + g2*(1-p)*d20 + g4(1-p)*d40 + p*f1 + g2(p)*d21 + g4(p)*d41 where f0 and f1 are frequencies at consecutive times t0 and t1 in the table p = (t-t0)/(t1-t0) g2(x) = x*(x*x-1)/6 g4(x) = x*(x*x-1)*(x*x-4)/120
