3DFast

3D Fast is a software suite that can be used to calculate 3D cosmic shear power spectra. It was used to generate the 3D cosmic shear power spectra for these papers:

• 3D Cosmic Shear: Cosmology from CFHTLenS

Details fo the code are as follows:

• Language: C
• Libraries used: CFITSIO, GSL, CLAPACK
• Other public code used: CAMB
• Architecture: The code is parallelisable and uses in-code POSIX threads

The code has the following functionality, it can

• 1) generate 3D cosmic shear power spectra
• 2) create Fisher matrix predictions for cosmic shear surveys
• 3) search cosmological parameter likelihood using an MCMC metropolis-hastings algorithm

If you would like to download the code, or contribute to its development, please email t.kitching@ucl.ac.uk
