2.  Peak Extraction

ExtractReflection.sit.hqx  for PowerMac

GUI-based application program and source codes written in C-language, for extracting experimental peak profile data from the lattice parameters and extinction rules.

3.  Profile Fitting

ProfSim.sit.hqx for PowerMac

GUI-based application program and source codes written in C-language, for simulating experimental peak profile by calculating convolutions of instrumental functions with symmetric peak functions.
Supported models are:

  1. Convolution of pseudo-Voigt (Thompson, Cox & Hastings model) with Bragg-Brentano instrumental function (Ida & Kimura model).
  2. Convolution of pseudo-Voigt (Thompson, Cox & Hastings model) with SR diffractometer instrumental function (Ida, Hibino & Toraya model)
  3. Convolution of extended-pseudo-Voigt (Ida, Ando & Toraya model) with SR diffractometer instrumental function (Ida, Hibino & Toraya model)
  4. Finger-Cox-Jephcoat model ...and some others.

4.  Deconvolution of Instrumental Functions

Deconv4.sit for Mac OS X

deconv4.zip for Microsoft Windows

Application program and source codes written in C-language, for deconvoluting the instrumental functions from data measured with Bragg-Brentano type diffractometers.

4-2  Synchrotron diffractometer

DeconvSR.sit.hqx for Macintosh (under construction)

Application program and source codes written in C-language, for deconvoluting the instrumental function from data measured with high-resolution synchrotron powder diffractometer.

5.  Projection of Crystal Structure

Cryst.sit.hqx for PowerMac (under construction)
