 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:
 0.623 0.530 0.324
