sbm.forecast(cl_syst, n_el=None, fsky=1.0, lmax=191, r0=0.0, tol=1e-08, rmin=1e-10, rmax=100, rresol=1000)[source]#

This function estimates the bias on the tensor-to-scalar ratio due to pointing systematics This function based on the paper: https://academic.oup.com/ptep/article/2023/4/042F01/6835420, P88, Sec. (5.3.2)

Parameters:

  • cl_syst (np.ndarray, 1d array) – residual B-modes power spectrum

  • fsky (float) – sky fraction

  • lmax (int) – maximum multipole considered in the maximization

  • rmin (float) – minimum value of r considered in the maximization

  • rmax (float) – maximum value of r considered in the maximization

  • rresol (int) – resolution of the grid in the r range
