sigma sections for ODF and orientation plotting

The MTEX default for plotting an ODF. Sigma sections are the pole figure of the c* axis, split up by sigma = phi1 - phi2. Unlike Euler angle sections they distort orientation space only mildly, so a component keeps its shape across the sections.

Syntax

oS = sigmaSections(cs1,cs2)
oS = sigmaSections(cs1,cs2,'sections',5)
oS = sigmaSections(cs1,cs2,'sigma',(0:15:90)*degree)

Input

cs1, cs2 crystalSymmetry, specimenSymmetry

Options

sections number of sections
sigma explicit section values

Class Properties

omega the sigma value of each section
h1, h2 the Miller the sections are built from
sR sphericalRegion each section is plotted on
referenceField S2VectorField sigma is measured against

Example

mtexdata dubna
odf = calcODF(pf,'silent');
plotSection(odf,sigmaSections(odf.CS,odf.SS))
pf = PoleFigure (y↓→x)
  crystal symmetry : Quartz (321, X||a*, Y||b, Z||c)
 
  h = (022̅1), r = 72 x 19 points
  h = (101̅0), r = 72 x 19 points
  h = (101̅1)(011̅1), r = 72 x 19 points
  h = (101̅2), r = 72 x 19 points
  h = (112̅0), r = 72 x 19 points
  h = (112̅1), r = 72 x 19 points
  h = (112̅2), r = 72 x 19 points
