Hi everyone, no major rush but there is a mismatch for the orientation labels in the IPF triangles (for HCP), please could they get swapped?

images show the same region plotted from aztec crystal 2.2 and defdap 0.93.5

best wishes,

This is the conclusion I came to when I compared the different programs.
