The calculator below takes an experimentally measured orientation as input and returns the Euler angles after the convention defined in Zambaldi & Raabe (Acta Mater. 2010). Further, it gives the in-plane rotation angles that will rotate the measured pile-up pattern according to the convention. Thereby the inverse pole figure of indentation patterns can be constructed from several indents in various orientations. IPF templates are available.
The Euler angles should be after Bunge convention (Z-X-Z) and rotate the laboratory frame into the crystal frame.
Euler angles (°) Label:
Euler angles (deg) ("")
The corresponding Z-vector (the indentation axis) in crystal coordinates: VAL
Spherical coordinates zeta and eta: VAL (deg)
The in-plane rotation to backrotate the experimental orientation into the one defined by convention  is VAL.
When rotating the actual topography data by this angle, keep in mind that it might be necessary to apply an additional in-plane rotation to align the data coordinate system with the RD-TD axes of the Euler angles.
