Notes. Radio continuum sources have been classified as follows (Col. 12): stellar winds (SW), jets (JET), opaque cores (OP; cf. Sect. 4.2), and H II regions (H II). Sources detected at one frequency only have not been classified (NA). (a) The 8 GHz flux of this source was extrapolated assuming an optically thin spectral index, cf. Sect. 4.2. (b) Tapering of 500 kλ at Ku band. (c) Sources excluded from Fig. 5 b: Lbol is uncertain because of high multiplicity in the field. (d)Since these sources were only detected at K band, and a reliable estimate of the 8 GHz flux is not available, they were excluded from the analysis in Fig. 5. (e) Maps cleaned with uv cut: > 100 kλ. (f) C-band data are from exp. 12B-044 and are centered at the frequency of 6.240 GHz. (g) Fluxes at the frequencies of 20.2 and 24.2 GHz, respectively. (h)Fluxes at the frequencies of 20.2 and 24.2 GHz, respectively. (i)This source was excluded from Fig. 5 a because it is not a thermal jet. (j) Resolved out/missing flux. (k) Maps cleaned with uv cut: > 100 kλ. (l) Maps cleaned with uv cut: > 200 kλ. (m) Tapering of 500 kλ at Ku band. (n) Fluxes at the frequencies of 5.0 and 7.0 GHz, respectively. (o)Fluxes at the frequencies of 20.2 and 24.2 GHz, respectively. (p)Maps cleaned with uv cut: > 100 kλ. (q) H2O masers are associated with VLA–1. (r) H2O maser luminosities are 0.3 10−5 and 0.4 10−5 L⊙ for VLA–1 and VLA–2, respectively. For the purpose of Fig. 5 b, the bolometric luminosity was split between VLA–1 and VLA–2. (s)Since H2O masers are associated with VLA–2, only this component was considered in Fig. 5 a. (t) The Ku-band map was cleaned with uv cut: > 40 kλ. (u) The 8 GHz flux of this source was extrapolated assuming an optically thin spectral index, cf. Sect. 4.2.

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.
