4. Reference

The corfu package contains the following functions:

• ptoxi()

• uneqt()

• eqt()

• wtocl()

• cltow()

---

corfu.ptoxi(k, p, q=0, limber=False)

compute 3d correlation function from power spectrum

Parameters

• k (array_like (N,)) – Wavenumbers.

• p (array_like (.., N)) – Power spectrum. Can be multidimensional. Last axis must agree with the wavenumber axis.

• q (float, optional) – Bias parameter for FFTLog.

• limber (bool, optional) – Compute Limber correlation function for equal time approximation. Default is False.

---

corfu.uneqt(theta, f1, f2, xi, progress=False)

unequal time projection

---

corfu.eqt(theta, f12, xi)

equal time projection

---

corfu.wtocl(theta, w, lmax)
