Notes. The ID is sorted in descending order of flux density F_ν. θ_maj, θ_min: measured major and minor FWHM. PA: position angle of the elliptical model. R_θ: Geometric mean FWHM in angular scale. R_p: Geometric mean FWHM in physical scale. R_{θ, dec}: deconvolved geometric mean FWHM in angular scale. R_{p, dec}: deconvolved geometric mean FWHM in physical scale. $⟨ T_{dust}^{leaf} ⟩$ $Mathematical equation: $\[\left\langle T_{\text {dust}}^{\text {leaf}}\right\rangle\]$$ : mean dust temperature of the leaf. M_leaf: Dendrogram leaf mass calculated from monochromatic flux. M_enc: Dendrogram leaf calculated from enclosed pixels. ℛ: Region flag (Y for young, I for intermediate, and E for evolved). Only the first ten rows are shown; the complete version will be published in CDS.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
