IRF

 

Diffraction geometry [ILOR]

Select different type of geometry.

 

Instrumental Resolution File [IRESO]

Define a instrumental resolution file.

 

Corrections

 

 

External corrections of Integrated / Profile Intensities [ICORR]

External corrections for intensities.

 

Preferred orientation [NORI]

Define is preferred orientation is used or not.

 

Correction for iluminated area exceeding the sample surface [SENT0]

Theta angle at which the sample intercepts completely the x-ray beam. Below SENT0 part of the beam doesn't touch the sample and the intensity of reflections below SENT0 have to be multiplied by  the factor:

 

                                                                    

 

Monochromator Polarization [CTHM]

Coefficient for monochromator polarization correction.

 

Polarization factor / Fraction mosaic-crystal [RKK]

Fraction mosaic-crystal for transmission geometry or Polarization factor in a synchroton experiment.

 

Absorption correction [TVM]

Absorption correction coefficient  (  is the effective absorption coefficient;  the radius or thickness of the sample), used only for refinement on cylindrical samples and flat samples with symmetrical  scanning (the scattering vector lying within the sample plane).

 

Asymmetry correction [RLIM]

Peaks below this  limit are corrected for asymmetry.

 

T.O.F. Absorption correction [IABSCOR]

Select a type of absorption correction for T.O.F. experiment.
