Left: Lp-band image of the MIR excess source IRS 5E before LR deconvolution. The arrows indicate the proper motions of the central source, the motion of the Northern Arm material and the motion of both relative to each other. The magenta line indicates the polarization. Right: The same source after LR deconvolution. The elongation of the source, the relative motion vector and the polarization all consistently indicate a bow-shock source. Contours indicate flux levels, in steps of 10% of the maximum flux.
