Notes. The columns give: ID, J2000 positions, magnitudes and errors in all bands: V, R, I, J, H, KS, [3.6], [4.5], [5.8], [8.0], and YSO classification. Near-IR photometry is from Omega2000 except for very bright or unresolved sources, where we use the NOTCam photometry. IRAC magnitudes that reach saturation are flagged as lower limits. The YSOs are listed in groups, first the 8 Class Is, then the 4 Class IIs, followed by 28 PMS stars with IR-excess emission. The last column gives the YSO class or the selection criterion, that is, excess in the K− [4.5] index (4) or excess in the H−KS index (5). The full table of 144 YSO candidates is available at the 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.
