FIT:    data read from 'Glider_velocity.dat' u 1:2
        format = x:z
        x range restricted to [420.000 : 460.000]
        #datapoints = 5
        residuals are weighted equally (unit weight)

function used for fitting: f(x)
	f(x)=a*x+b
fitted parameters initialized with current variable values
