CROSS_CMBFAST CODE

Post by Pier Stefano Corasaniti » September 11 2006

For those interested in CMB-LSS cross-correlation, I am making publicly available my extended version of CMBFAST4.5 for the computation of the ISW-correlation (2-point angular and power spectrum).

In the present version the cross-correlation computation is implemented only on flat models. Dark energy models with perturbations are specified by a constant equation of state (w) or a linear parameterization in the scale factor (w_0,w_a) and constant sound speed.

The code can be easily modified for studying the ISW-correlation in more complicated models. For reference see astro-ph/0504114. For a similarly modified version of CAMB it will take me some time as I am facing a relocating period.

The code can be found at:

In case of bugs, problems or questions just email me.
Cheers,

Pier-Stefano

opsss... I just realized that I quoted the wrong reference to my own paper, the correct one (as you may have notice) is astro-ph/0504115. See also on the updated CROSS_CMBFAST webpage.

Thanks Alessandro ;-)
