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:

3.30 1.29 2.78
