We present the COFFE (COrrelation Function Full-sky Estimator) code, available for download at github.com/JCGoran/coffe.
The code computes the galaxy 2-point function and its multipoles in linear perturbation theory, including all relativistic and wide angle corrections. COFFE also calculates the covariance matrix for two physically relevant estimators of the correlation function multipoles.
The outputs of COFFE are:
- Angular two-point function
- Two-point function
- Multipoles of the two-point function
- Redshift averaged multipoles of the two-point function
- Covariance matrix
