Fitting results of various observational parameters as a linear function of six selected observational eigenparameters. The observational eigenparameters are ﹩\mathrm{log}\,{V}_{{\rm{span}}}﹩, R₂(¹³CO), ﹩\mathrm{log}\,{l}_{{\rm{maj}},{\rm{ang}}}﹩(¹³CO), ﹩\mathrm{log}\,{T}_{{\rm{peak}}}﹩(¹³CO), ﹩\mathrm{log}\,{T}_{{\rm{peak}}}﹩(C¹⁸O), and ﹩\mathrm{log}\,{\overline{T}}_{{\rm{peak}}}﹩(C¹⁸O). These parameters are in log form, so the fit is equivalent to a power-law fit to the original parameters, except for the morphological parameters (R₂ and θ). The fitting is weighted by the significance of ﹩\overline{W}﹩(¹²CO), indicated by colors from blue to red. The magnitude of ﹩\overline{W}﹩(¹²CO) is shown in its plot in the third row. All fitted parameters are available in Science Data Bank at doi:10.57760/sciencedb.32354.
