Spectra of the lines investigated to search for outflows toward Sgr B2(N3) (top row) and Sgr B2(N5) (bottom row). The dashed vertical line marks the systemic velocity of the source and the high velocity wings are highlighted in blue and red. The magenta spectrum represents our best-fit model while the green spectrum shows the model that contains all the identified species. The rest frequency and upper level energy (in temperature units) of each transition are indicated in each panel.
