Class
NumCosmoMathFftlogTophatwin2
Description [src]
final class NumCosmoMath.FftlogTophatwin2 : NumCosmoMath.Fftlog
{
/* No available fields */
}Logarithm fast fourier transform for a kernel given by the square of the spherical Bessel function of order one.
This object computes the function (see NcmFftlog)
$$Y_n = \int_0^\infty t^{\frac{2\pi i n}{L}} K(t) dt,$$
where the kernel is the square of the top hat window function in the Fourier space $K(t) = W(t)^2$,
\begin{eqnarray}
W(t) &=& \frac{3}{t^3}(\sin t - t \cos t) \
&=& \frac{3}{t} j_1(t),
\end{eqnarray}
and $j_\nu(t)$ is the spherical Bessel function of the first kind.
Properties
