Spectra of the HCl⁺ and HCl⁺ 1₁₁-0₀₀ (para) line and other species, all observed by ALMA between April and June 2012, toward the PKS 1830−211 SW image (left) and the NE image (right). The hyperfine structure for the HCl⁺ para-line is shown (top-left). That for HCl⁺ is similar. The Gaussian fits are overlaid in light yellow. The redshifted line frequency is given in the bottom-right corner of each box. A detailed presentation of the ALMA data is given by Muller et al. (2014).
