Lyα equivalent width versus filament impact parameter for absorbers with velocities within 1000 km s⁻¹ of the nearest filament segment. Open circles indicate absorbers that are associated with a galaxy (passing it within 1.5 R_vir and Δv < 400 km s⁻¹), and closed circles indicate absorbers that are not associated with a (known) galaxy. The different colours indicate the individual filaments.
