Emu CMB is a fast emulator the CMB temperature power spectrum based on CAMB (Jan 2010 version).
- Inputs for 6 parameter cosmological model:
- ln(1010 As)
- 100 &theta*
- &Omegac h2
- &Omegab h2
- Maximum multipole l = 5238
- Lensing included
- Matches CAMB output to 0.6% over WMAP5 prior parameter range
- Python and IDL versions
The construction and performance of the code are described in detail in Schneider, Holm & Knox (2010) (arXiv:1002:1752).
CAMB parameter file used to generate one of the design runs.

We have tested the interpolation accuracy by interpolating to 100 new locations within a 4-sigma hypersphere in our fiducial WMAP5 prior distribution in the 6-parameter design space.
Here are the fractional interpolation errors in the power spectra:
