Schematic view of a topographic profile showing the elements to define Ra and Rt roughness parameters. Blue dotted line: base line of the profile; Zp: height of the highest peak; Zv: deepest valley; Zmax: parallel line of the baseline that marks; Zmin: line parallel to the baseline that marks the deepest valley; brown arrows: the five highest peaks; green arrows: the five deepest valleys
