final class NumCosmo.DataPlanckCommander : NumCosmoMath.Data
{
/* No available fields */
}Planck low-$\ell$ commander (gibbs_gauss) temperature likelihood, native port.
A Gaussianized Blackwell-Rao likelihood over the low-$\ell$ TT band. Each theory
$D_\ell = C_\ell \ell(\ell+1)/2\pi$ (with $C_\ell$ divided by the calibration
$A_\mathrm{planck}^2$) is mapped through a per-$\ell$ cubic spline to a
Gaussianized variable $x_\ell$, and
$$\ln L = -\tfrac12 (x-\mu)^\mathsf{T} P (x-\mu) + \sum_\ell \ln\frac{dx_\ell}{dD_\ell} - \mathrm{offset},$$
where $P$ is the inverse of the (band-limited) covariance and the offset fixes
$\ln L(\mu_\sigma)=0$. This NcmData reports $-2\ln L$; unlike the clik wrapper
it can also resample.
Constructors
nc_data_planck_commander_new
Builds a fully-specified NcDataPlanckCommander (calibration defaults to
A_planck). The theory $C_\ell$ source is set separately.
