Notes. We show the short-spacing corrected and u − v trimmed data set at their native and best-common 4″ ≈ 150 pc spatial resolution. Column (1) Molecules and their transition. (2)−(4) Characteristics after the short-spacing correction at their native resolution and recovered flux compared to PdBI only data set (see Table 3). (5)−(12) We quote the mean for the central sight line, i.e. aperture of 4″ ≈ 150 pc. (5) Integrated intensity. (6) Peak temperature of the spectrum. (7) Root mean square (rms) noise. (8) Signal to noise. (9)−(12) Ratios of molecular species with CO, HCN and ΣSFR. The Iline/ΣSFR ratio results in units of K km s−1/(M⊙ yr−1 kpc−2).
