FIT:    data read from 'curve_fit.dat' using 1:2
        format = x:z
        x range restricted to [0.00000 : 18.0000]
        #datapoints = 5
        residuals are weighted equally (unit weight)

function used for fitting: a*x*x + b*x + c
fitted parameters initialized with current variable values
