Some of the parameters depend on the definition of a local minimum and a local maximum. It is therefore important to include the measurement conditions when reporting roughness data. Note, also that roughness values depends strongly on measurement conditions especially scan range and sample density. Before the calculation of the roughness parameters we recommend carrying out a slope correction by a 2 nd or 3 rd order polynomial plane fit. The table lists the roughness parameters by their symbol, name, corresponding 2D standard and unit. In most applications where RMS is called.
