Spectra extracted from selected positions in the AGN position (A) and on the SF ring (B-I) of NGC 1097. Frequency span has been cropped with respect to that of Fig. 1 removing the line free frequencies at the edges of both sidebands. Flux density scale has been multiplied by a factor of ×4 in the regions (defined by the vertical dashed lines) containing the fainter lines to improve their visualization. Molecular fit to the observed emission is represented by the red line. Non-detections are presented as the 3σ limit Gaussian profiles.
