Normalized surface brightnesses as a function of distance to the IF (0.228 pc or 113.4^′′ from θ¹ Ori C) along a cut crossing the mosaic (see Fig. 2 for the location of the cut). Normalization factors are listed in W m⁻² sr⁻¹ in parentheses for each surface brightness. As the cut is not perpendicular to the IF and distances are given along the cut, a correction factor of cos(19.58°)=0.942 needs to be applied to obtain a perpendicular distance from the IF. The vertical dash-dotted lines indicate the position of the IF, DF 1, DF 2, and DF 3, respectively, from left to right, where the DFs are defined by the maximum intensity of H₂ emission (Peeters et al. 2024). The vertical dashed lines indicate the location of the proplyds 203–504 (left) and 203–506 (right).
