Correlation coefficient, 𝒞_jj′ (Eq. (29)), expressed in percent, for the 325 possible pairs of Gaussian kinematic components j and j^′ (j ≠ j^′) extracted with ROHSA in the Hi and CO spectral cubes of the G139 region. The names of the 26 components, together with the mini-maps of their dust intensities, are shown along the top row and left column. Mini-maps of 𝒞_jj′ are displayed in the upper-right half of the figure. The weighted average values of 𝒞_jj′ over the 26 × 26 pixels, ⟨𝒞_jj′ ⟩ (Eq. (30)), are indicated in the lower-left half, with red or light-blue shading according to whether ⟨𝒞_jj′ ⟩ ≥ 50% or ⟨𝒞_jj′ ⟩ < 50% and with a level of shading increasing with increasing ⟨𝒞_jj′⟩. Pairs for which ⟨𝒞_jj′⟩ ≥ 50% have their two components j and j^′ combined and assigned to a same cloud. The 26 components are thus grouped into seven different clouds, ℂ₁, …, ℂ ₇, as indicated along the diagonal.
