Initialize an elliptical Navarro-Frenk-White mass distribution lens (eNFWMDLens) with the given parameters. The lens model can be initialized with either the concentration c or the scale radius x_s. If both are provided, c will be used to calculate x_s and the input x_s will be overwritten.

Arguments

• cosmology::AbstractCosmology: Cosmology object.
• z_d::Real: Redshift of the lens.

Keyword Arguments

• x_c::Real = 0.0: x-coordinate of the lens (in $\rm \mathbf{arcseconds}$).
• y_c::Real = 0.0: y-coordinate of the lens (in $\rm \mathbf{arcseconds}$).
• mass::Real= NaN: Mass of the lens (in $\rm \mathbf{M_\odot}$).
• x_s::Real = NaN: Scale radius (in $\rm \mathbf{arcseconds}$).
• c::Real = NaN: Concentration of the lens.
• eps::Real = NaN: Ellipticity.
• pa::Real = NaN: Position angle (in $\rm \mathbf{deg}$).
