 Method, part 1, Chebychev polynomial, (Watkin, 1994, Prince, 1982) 

 [weight] = 1.0/[A~0~*T~0~(x)+A~1~*T~1~(x) ... +A~n-1~]*T~n-1~(x)] 

 where A~i~ are the Chebychev coefficients listed below and x= Fcalc/Fmax 

 Method = Robust Weighting (Prince, 1982) 

 W = [weight] * [1-(deltaF/6*sigmaF)^2^]^2^ 

 A~i~ are:
