NFWPotential¶

NFW potential of gNFW need the following parameters:
x_centre, y_centre, ellipticite, angle_pos, alpha, scale_radius_kpc, concentration, z_lens .

alpha = 1.0 corresponds to a regular NFW profile.

e.g. of lenstool NFW parametrization.

potential 1

profil 12
x_centre 0.00
y_centre 0.00
ellipticite 0.0
angle_pos 0.0
alpha 1.0
scale_radius_kpc 30.0
concentration 5.5
z_lens 0.2
end

NOTE: If you want to use the generalized NFW profile, you need to prepare the lenstool.tab lookup table with this command:
make table
