A linear calibration factor can be applied using the Dimensions and Units tool, as outlined
above.

Apply Non-Linear Correction in Gwyddion
More complicated functions, such as a polynomial function, can be applied to a datafield (the
Gwyddion term for a scan) by using Data Process > Multidata > Arithmetic. The function
calculated can be applied to the datafield ‘d1’. Once applied, this will create a new calibrated
image. Check that the data is scaled appropriately using either method for calculating a
calibration factor.
