Comparison between the MIRI-MRS data obtained using the JWST pipeline cube_build (Col. 1), the result of the coarse stitching procedure (Col. 2), the stitched data produced by Haute Couture (Col. 3), and this final product convolved with a Gaussian filter (Col. 4) in each channel at a given wavelength. The same color bar (in MJy/sr) is used in each row, and the data in Cols. 1, 3, and 4 share the same mask. The red circles correspond to the emplacement of the d203-506 protoplanetary disk. The loss of spatial resolution is also clearly visible when performing a coarse stitching.
