Fig. 7

Column density ratios (in black) of several species (in red) relative to SH+ (in green) toward the SW image of PKS 1830−211. Opacity spectra were smoothed by five channels to improve the S/N in individual channels. The column density ratios are calculated only where both species have opacity S/N larger than five.
