halomod.profiles.Einasto.u¶
- Einasto.u(k, m, norm='m', c=None, coord='k')¶
The (optionally normalised) Fourier-transform of the density halo_profile
- Parameters
k (float or array of floats) – The radial wavenumber(s). The units vary according to
coord
m (float or array of floats) – The mass(es) of the halo(s)
norm (str, {
None
,``m``,``rho``}) – Normalisation of the density.c (float or array of floats, default
None
) – Concentration(s) of the halo(s). Must be same length asm
.coord (str, {
k
,``kappa``}) – What the radial coordinate represents.r
represents physical wavenumbers [units h/Mpc].kappa
is in units of the scale radius, kappa = k*rs.
