The Bianchi2 package provides functionality to simulate 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 Anthony Lasenby (not yet published) that incorporate a cosmological constant. Functionality is provided to compute the induced fluctuations on the sphere in either real or harmonic space.
