Line-of-sight shear in 45 SLACS lenses is often larger than N-body expectations (mean |γ_LOS| ≈ 0.085–0.11), and adding mass octupoles or checking image properties does not remove the excess.

Line-of-sight shear in SLACS strong lenses II: validation tests with an extended sample
Line-of-sight shear in 45 SLACS lenses is often larger than N-body expectations (mean |γ_LOS| ≈ 0.085–0.11), and adding mass octupoles or checking image properties does not remove the excess.
