Indexing

Indexing of the detected lines is performed by a search through the reflections in kinematically simulated diagram. For a given line marked in the pattern,  if there is an (hkl) reflection with line in the diagram closer than a certain limit then the indices (hkl) are ascribed to the marking line in the pattern. The limit can be changed in “Settings/Miscellany/Indexing”. The angle and distance have the same meaning as Duda-Hart radius-angle or {rho, theta} line parameters typically used for calculating the Hough transform. Right click on  the "Indexing" button gives distances between the (kinematically) simulated lines and marking lines given as deviations of the Duda-Hart  parameters; the units are {pixel/10, deg/100}.
