Fig. B.2


Examples of the N2H+ (1-0) ALMA spectra found in Orion: from left to right: (1) observed spectrum and best-fit solution: (2) individual components identified by the fit; (3) zoom-in on the (JF1 F) = (101 − 012) hyperfine component; (4) residual spectrum after the subtraction of the best-fit solution. For comparison, the best-fit solution (either single or multiple) is displayed in all subpanels in green. Each individual velocity component is denoted in red and blue in panels 2 and 3. From top to bottom: (a) single component; (b) well-resolved multiple components; (c) superposition of components; (d) problematic spectra.
