Examples of intensity gaps observed in overlapping areas of adjacent cubes, obtained from MIRI-MRS data collected within the PDRs4All program (see Sect. 3.1 for more details). The spectra displayed correspond to the average spectra over the entire field of view for two overlapping sub-channels. Panel a: channel 2-medium and 2-long. Panel b: channel 2-long and 3-short. Panel c: channel 3-short and 3-medium. Fringes can be seen in Panel a, corresponding to a well-known phenomenon already documented by Argyriou et al. (2020).
