Line maps of PACS with visible lines for HH354 IRS. The maps show a specific bandwidth around emission lines of molecularor atomic transitions in the spectra coming from the integral field spectroscopy from PACS. The bandwidth is defined for each source by a fitting routine. A threshold cuts off noise below a specific value. For molecular lines, the species is mentioned in the upper left corner of the plot, together with the energy transition for CO and its isotopolog and the wavelength for other molecules. For the atomic lines, next to the isotope we give the frequency of the transition. The circle in each of the plots represents the coordinates of the optical FUor/EXor.
