Groups 3, 4, 5, and 6 bow-shock candidates WISE images. Red: band 4, 22.2 μm. Green: band 3, 12.1 μm. Blue: band 1, 3.4 μm. The label stands for the name in the final list of E-BOSS r2 BSCs. We have drawn μ_αcosδ and μ_δ to compose the total μ. The thick vectors represent the measured Hipparcos proper motions (van Leeuwen 2007), and the thinner vectors stand for the star proper motions but corrected for the ISM motion caused by Galactic rotation. The vector lengths are not scaled with the original values.
