Bow shock models with corresponding χ²-values for six different rotation angles α under five different inclination angles i. All models were simulated for a constant stand-off distance R₀ = 3.5 × 10¹⁶ cm with a constant position angle PA = 10°. Black lines represent intensity contours derived from L′-band images. Red lines correspond to simulated bow shock model intensity contours. The best-fitting plots are marked by the blue box. The axes of each model show the relative RA and Dec with respect to the central star in units of pixels, with one pixel corresponding to 0.027′′.
