Notes. The dual-band source catalog. Only the top three rows of each cloud are shown and the complete version can be found in 10.5281/zenodo.15068333. The sources are sorted by the dual-band combined significance level of getsf core extraction. R.A. and Dec.: right ascension and declination of equatorial coordinate system. θ_maj × θ_min: measured major and minor FWHM angular sizes. PA: position angle. Size: the linear FWHM size deconvolved from the synthetic beam. $I_{ν}^{peak}$ $I_{\nu}^{\text{peak}}$ : peak intensity. $S_{ν}^{tot}$ $S_{\nu}^{\text{tot}}$ : integrated flux over source.

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.
