<p>scalars_movie.mp4 : Bianchi VIIh/VII0 scalar modes, imprint on the CMB for varying morphology parameters (matter and dark-energy density, rotation scale of shear principal axes)</p>
<p>vectors_movie.mp4: Bianchi VIIh/VII0 vector modes, imprint on the CMB for varying morphology parameters (matter and dark-energy density, rotation scale of shear principal axes)</p>
<p>tensor_movie.mp4: Bianchi VIIh/VII0 regular tensor modes, imprint on the CMB for varying morphology parameters (matter and dark-energy density, rotation scale of shear principal axes)</p>
<p>Additional fixed parameters for the three animations above:<br />
cold-dark-matter physical density: 0.112<br />
baryon physical density: 0.226<br />
Pattern orientation additionally fixed to put spiral in full view</p>

baryon physical density 0.0226<br />
matter density: 0.27<br />
