Notes. The location and sizes of the dents are shown in Fig. 3. (α)One arcminute corresponds to the physical size of 0.12 pc at the distance of the Orion Nebula (414 pc; Menten et al. 2007). The error in size is around 10%. (b)I[CII] denotes the integrated intensities of the dent. The values indicate which component dominates [СII] emission at the dent position. If the value in the Veil and the OMC columns are > 1, that dent has brighter [С ii] emission. For fit results, see Table A.1. (c)d, f, and a denote the distance between star and the Veil surface, the collimation factor and opening angle (in degree) of possible outflows, respectively, f and a are given for distances of 2.0 pc. See Sect. 4 for more detail.
