This
deformation is such that any reciprocal line, passing through
the
centre of the reciprocal lattice, appears in the diagram as a line of
spots lying on a straight line with slope 2. Furthermore, the
angle between two reciprocal lines that intersect each other in the
reciprocal lattice is shown in
the diagram as the distance between two parallel lines, as it is
shown in the figure below:

diffraction spots. These templates were used for the measurements of
diffraction intensities in a manual photometer, so one could identify
all spots with their Miller indices.
