2.  xQML tests :

2.1  EB xqml extension :

  • EB pixel covariance matrix : see end of file Attach:pixel_covariance.pdf
  • matrix ds_dcb is extended to EB spectrum
  • S matrix is also extended to EB spectrum
  • To test the xQML estimator, we generate CMB maps using the usual fiducial model, and add a non-zero EB spectrum given by {$ C_\ell^{EB} = c \cdot\sqrt{C_\ell^{EE} C_\ell^{BB}} $} where {$ c \in [0,...,1] $} is a correlation paramater.
  • Voir papier Planck birefringence : Planck intermediate results. XLIX. Parity-violation constraints from polarization data
  • mode-mode matrices are now of dimension [3*nbins, 3*nbins].

2.2  Results :

  • ns= 4
  • 0.1 muK-arcmin
  • the red curve 'fisher' is not the fisher error but the mode-counting error (forget to correct).
