BIANCHI PACKAGE
Simulating Bianchi induced temperature fluctuations in CMB maps
---------------------------------------------------------------
DESCRIPTION
This package provides functionality to support the simulation of
Bianchi Type VIIh induced temperature fluctuations in CMB maps
of a universe with shear and rotation. The implementation is
based on the solutions to the Bianchi models derived by
Barrow et al. (1985), which do not incorporate any dark
energy component. Functionality is provided to compute the
induced fluctuations on the sphere directly in either real or
harmonic space.

REFERENCE
The BIANCHI package was written originally to determine whether
recent evidence for non-Gaussianity in WMAP CMB observations were
due to Bianchi contributions. The code is based on solutions to
the Bianchi models derived by:
Barrow J. D., Juszkiewica R., Sonoda D. H., 1985, MNRAS, 213, 917
If you use the code to produce published works please reference
