Most functions are protected, only to be accessed, internally or from the friend class PowderPattern.
|
Calc the powder pattern. As always, recomputation is only done if necessary (ie if a parameter has changed since the last computation) Implemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
Calc the integrated powder pattern. This should be optimized so that the full powder pattern is not explicitely computed. Implemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
Get the integration limits (first and last pixels) around each reflection, if this component has Bragg reflections. Used for integrated R(w) factors. The limits currently go from -2*FWHM to +2*FWHM. returns a pointer to the min and max pixels arrays (null pointers if no reflection for this phase). Implemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
Name for this class ("RefinableObj", "Crystal",...). This is only useful to distinguish different classes when picking up objects from the RefinableObj Global Registry Reimplemented from ObjCryst::RefinableObj. Reimplemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
Get the calculated powder pattern for this component. Note that the pattern is not scaled. Implemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
Get the variance associated to each point of the calculated powder pattern, for this component. \warning: this is experimental, with the aim of using Maximum Likelihood to improve structure determination. Implemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
Get the integrated values of the powder pattern. \note: the integration intervals are those given by the parent PowderPattern, so that all PowderPatternComponent's intervals are taken into account This avoids explicitely calculating the full profile powder pattern. Implemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
Get the variance associated to each point of the calculated powder pattern, for this component (integrated version). \warning: this is experimental, with the aim of using Maximum Likelihood to improve structure determination. Implemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
Is this component scalable ? This is used by the PowderPattern class, which fits all pattern components using scale factors. Some components may not need to be scaled: background components, which are assumed to be absolute. |
|
For internal use only. This will be called by the parent PowderPattern object, before calculating the first powder pattern. Or maybe it should be called automatically by the object itself... Reimplemented from ObjCryst::RefinableObj. Implemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
Set the maximum value for sin(theta)/lambda. All data above still exist but are ignored for all calculations. Implemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
For internal use only. Set the PowderPattern object which uses this component. This sets all necessary pattern parameters (2theta range, wavelength, radiation type...) accordingly. Implemented in ObjCryst::PowderPatternBackground, and ObjCryst::PowderPatternDiffraction. |
|
The calculated component of a powder pattern. It is mutable since it is completely defined by other parameters (eg it is not an 'independent parameter') |
