A stand alone version of the Delta Sigma code currently used in CosmoSIS that doesn't require the use of the CosmoSIS data block.
To run with a python interface, from Delta-Sigma/ run:
$make
To compile a C standalone library, run: $make ALONE=yes
You are required to have the GSL installed to run this code, and have the appropriate flags set up. Specifically, you need to have GSLI pointing to gsl/include and GSLL pointing toward gsl/lib.
For an exmaple of how to run, you can use:
$python example.py
If you want to change cosmologies then you have to supply a different power spectrum and change the paths around in example.py
