Determination
of profile parameters.
Each X-ray powder diffraction pattern contains
a number of peaks the profile parameters of which are to be
determined either by direct analysis or by fitting.
Profile parameters :
- Height - given in cps
- Position - given in 2 q units
- FWHM - full width at half
of maximum (halfwidth) either in 2 q (deg) or in
reciprocal units (1/d), optionally in Output.
- Integrated intensity -
given in 2 q units
- Integral breadth -
integrated intensity divided by the peak height either 2 q (deg) or
in reciprocal units (1/d), optionally in Output.
- Center of gravity - given
in 2 q units
- Shape parameters -
connected here to the exponent of the Pearson function
describing the profile ( default value) or corresponding
function.
