Observed MIRI-MRS spectrum (blue) centered around H₂ v = 0 pure rotational lines from the S(7) line in the top-left panel to the S(0) line in the bottom-middle panel. The best-fit Gaussian model is presented in orange in each panel. All presented lines are considered detected except for the S(0) line since the flux is similar to that of several strong residual fringes located in the vicinity of the S(0) line.
