Best-fit relations between the [Nii] 205 μm line emission and various parameters considered in this work, expressed as log 10(F[ NII] 205/W m-2 sr-1) = c + mlog 10x, with the corresponding 1σ errors.

Notes. We also state the scatter in dex (σ), Spearman (ρS), and Pearson (ρP) coefficients. For M 83, the limited case excludes the central pixels (log 10F24(W m-2 sr-1) > −4.4).
