Abstract Surface performance is critically influenced by topography in virtually all real-world applications. The current standard practice is to describe topography using one of a few industry-standard parameters. The most commonly reported number is \(R\)a, the average absolute deviation of the height from the mean line (at some, not necessarily known or specified, lateral length scale).
