Notes. (1) Values for the upper energy levels (Eu), without hyperfine structure, are taken from the Leiden Atomic and Molecular Database (LAMDA; Schöier et al. 2005; van der Tak et al. 2020). (2) Effective excitation density at 10 K (Shirley 2015). (3) The footprints of the different IRAM-30 m data are color-coded in Figs. 1 and 2: 032-12 (black), 034-16 (brown), 120-20 (gold), 133-22 (blue), and 060-22 (red).(*) No data available.(**) ALMA-alone maps.
