FIT:    data read from "c44.eng" using 1:6
        #datapoints = 6
        y-errors assumed equally distributed

function used for fitting: e(c44,a,b,c,x)
use actual parameter values


Initial set of free parameters:


Iteration 0
chisquare : 0.665135          relative deltachi2 : 0
deltachi2 : 0                 limit for stopping : 1e-05
lambda	  : 0.01

actual set of parameters

c44             = 1
a               = 1
