class Sersic

Elliptical Sersic

surface_brightness(I_eff=1.0, theta_eff=2.0, n=4.0, phi=0.0, q=1.0, center_x=0.0, center_y=0.0)

evaluate_surface_brightness(x, y, I_eff=1.0, theta_eff=2.0, n=4.0, phi=0.0, q=1.0, center_x=0.0, center_y=0.0)

Returns the surface brightness at the given position (x, y)

class Shapelets

Elliptical Sersic

The implementation uses functions from lenstronomy (, Birrer et al. [BirrerShajibGilman+21]), based on the developments of Refregier [Refregier03].

surface_brightness(amps=0, n_max=0, beta=0, center_x=0, center_y=0)

evaluate_surface_brightness(x, y, amps=0, n_max=0, beta=0, center_x=0, center_y=0)

Returns the surface brightness at the given position (x, y)

class Uniform

Uniform light distribution

surface_brightness(A=1.0)

evaluate_surface_brightness(x, y, A=1.0)

Returns the surface brightness at the given position (x, y)
