PLOT/RESIDUAL [ord1,ord2]
	plot dispersion residuals in echelle reduction
\us\pu
Purpose:    
            Plot the residuals of the wavelength fit in the echelle reduction
            The auxiliary table LINE is used by this command
            Residuals are plotted order by order if the parameters are
            specified.

Syntax:     
            PLOT/RESIDUAL [ord1,ord2]
\ys\pa
            ord1,ord2 = optional screen order range. If omitted the
                        complete order range is plotted.

Note:       
            The command is used to control the dispersion coefficients
            at the end of the wavelength calibration step
