3C 445, BLO, 1″ = 1.07 kpc. The black circle in the first panel has a diameter of 3 times the seeing of the observations; the dashed line in the second panel marks the radio position angle. In this source the outflowing gas assumes a flipped C shape extended by ∼8.60 kpc. The flux is approximately constant throughout the emission region while the velocity of the gas is major in the central area and decrease towards the two extremities. Here the emission lines are blueshifted showing velocities up to ∼ − 2160 km s⁻¹ (the maximum velocity reached between the BLOs). At the distance of ∼1.50 kpc from this region a smaller redshifted area is detected with dimensions of ∼3 kpc, here the gas reaches velocities down to ∼1100 km s⁻¹. The energy is higher in correspondence of the highest blueshifted velocities.
