The dark ones are normally drawn to provide contrast when the background grey-scale image is strong. DARKLINE is used to control the grey level, after scalings and FUNCTYPE (in the range 0 - 1) at which the switch to dark is made. The default value is 0.33. Tasks: GREYS.......Make a grey-scale plot with contours. PCNTR.......Make a grey-scale, contour, and polarization vector plot. ----------------------------------------------------------------
