Symmetrically equivalent orientations (with respect to the sample symmetry)

[saoussen ouhiba]

Hello,

I am trying to measuring volume fraction of different texture components (copper, brass and S) in a rolled sheet of aluminum alloys. For this purpose, do I need to consider symmetrically equivalent orientations as shown in the script below although I have specified the sample symmetry as Orthorhombic?

Thank you in advance for your help,

Saoussen

cs = ebsd_merged_rotated('Aluminum').CS;
ori = ebsd_merged_rotated('Aluminum').orientations;
ori.SS = specimenSymmetry('mmm');
ss = ori.SS;
odf = calcODF(ori,'halfwidth',8*degree);

% definition of copper orientation
copper = orientation.copper(cs,ss);
copper2 = orientation.copper2(cs,ss);

% definition of brass orientation
brass = orientation.brass(cs,ss);
brass2 = orientation.brass2(cs,ss);

% definition of S orientation
S = orientation.SR(cs,ss);
S2 = orientation.SR2(cs,ss);
S3 = orientation.SR3(cs,ss);
S4 = orientation.SR4(cs,ss);

symmetrically equivalent orientations are considered automatically.
