Description
The kernel is given by \begin{equation} W^g (z) = b(z) \frac{dn}{dz} + \frac{3\Omega_m}{2c} \frac{H^2_0}{H(z)} (1+ z) \, \chi(z) \, (5s-2) \, g(z) \end{equation} where \begin{equation} g(z) = \int_z^{z_{*}} dz^\prime \left( 1 - \frac{\chi(z)}{\chi(z^\prime)}\right) \frac{dn}{dz^\prime}$. \end{equation}
$\frac{dn}{dz}$ is the (automatically normalized) redshift distribution of galaxies (implemented as a NcmSpline), $ b(z)$ is the large-scale clustering bias and $s$ is the magnification bias. $b(z)$ can be a single number or a NcmSpline.
