Results of UMSCANGALACTIK applied to the line-of-sight velocity maps of our galaxy sample at different inclinations. Top panels: HDBSCAN clusters in the UMAP bidimensional projection of the line-of-sight velocity maps of galaxies observed at 60, 45, 30, and 20 degrees. The outliers of the method are shown as grey dots. Middle panels: Distributions of D/T on each projection. The colour bar limits are fixed to the 10th and 90th percentiles of the variables. Bottom panels: λ_R − ε plane. The symbols depict clusters following the same colour-coding as in the top panels. We include the criterion in Eq. (1) depicted by the black solid lines.
