Notes. Parameters are, in order, lens potential centre (x₀, y₀), lens mass elliptical components (ϵ₁, ϵ₂), EPL Einstein radius θ_Ein^lens, EPL density slope γ^lens, elliptical shear components (ϵ₁^sh, ϵ₂^sh), effective Einstein radius R_Ein, and the total mass within it M_Ein. Columns represent individual datasets or models (refer to text for details).
