Example spectrum of all molecular transitions fitted with XCLASS toward core 1 in ISOSS J22478+6357. In each panel, the observed spectrum of the emission line and the corresponding XCLASS fit are presented by the black and red lines, respectively. The green dotted line shows the 3σ_line level of the transition (Table 3). The gray dashed line indicates the rest frequency of the transition (Table 2). If XCLASS fits were discarded no fit is shown (the constraints are explained in Sect. 4.6). An example spectrum of core 1 in ISOSS J23053+5953 is shown in Fig. B.2.
