Panels a and b: variation of the HCO⁺(2−1) intensity and the HCO⁺(2−1)/HCN(2−1) ratio as a function of the SFR traced by L_TIR for the LMC (blue upward triangles) and SMC (red downward triangles) pointings. Intensities are in units of K km s⁻¹. The light and dark blue squares indicate the individual detections from the LMC spectral maps (18″ pixels) detected at a 3 and 5-σ level, respectively. Panel a: the dashed line indicates the linear fit to the data. The Pearson’s correlation coefficient is indicated Panels c and d: same but with colors indicating the star-forming region of each resolved element. Black triangles indicate LMC and SMC pointings shown with their corresponding DeGaS-MC numbers.
