Miller indizes on a four circle diffractometer. Hklscan operates with
a single detector. Hklscan2d does the same as hklscan but for the
position sensitive detectors, saving data into NeXus files. Hklscan
and Hklscan2d share the same syntax.
Prerequisite for this is
the existence of a scan object and the hkl-object for doing crystallographic
calculations. Make sure the properties of the hkl object (UB, wavelength, NB)
have some reasonable relation to reality, otherwise the diffractometer may
