DeGaS-MC pointing campaign: the positions of our pointings are indicated by the red crosses overlaid on the LMC and the SMC Herschel 500 μm observations (FWHM = 36″). An example of the HCO⁺(2−1) and HCN(2−1) spectra obtained towards regions LMC #5 and SMC #5 are shown (2 km s⁻¹ spectral resolution). The x-axis is expressed in velocity with respect to the systemic velocities (v = 0 corresponding to 262.2 km s⁻¹ for the LMC and 158 km s⁻¹ for the SMC). The catalogue of HCO⁺(2−1) and HCN(2−1) spectra is shown in Figs. A.1 and A.2. The yellow squares indicate the position of the sources targeted during the follow-up mapping campaign (see Sect. 2.2). Please note that the areas mapped are ∼4′ × 4′, i.e., smaller than these squares.
