Derived rotational temperature (T_rot; top) and total column density (N_tot; bottom) for each species and region. The order of the regions follows the layout of the GMCs/SSCs of the CMZ from north-east to south-west as shown in Figure 1. Top: when two gas components were fitted in the RDs, the T_rot of the two components are indicated. Bottom: column densities derived for GMC scales (θ_s = 1.6″; bottom part) and pSSC scales (θ_s = 0.12″; top part). For the species (CH₂NH and C₂H₅OH) and region (GMC 7), where only one gas component was fitted, we calculated the column densities for the two scales. For the other regions and species, we attributed the first component to an emission coming from GMC scales and the second component to an emission coming from pSSC scales. In the cases of NH₂CHO and CH₃CHO, only one component was fitted for pSSC 2 and pSSC 5, respectively.
