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.
