Notes.

( * )

Src # 405: All energies and peak luminosities are considered highly uncertain because of the large discrepancy between optical and X-ray extinction estimates (Sect. 5).

( † )

Src # 502: X-ray flare detected with 4.5 counts. No estimate of extinction was possible since AV is not available and NH could not be derived from the fit of the X-ray spectrum because of its low statistics.

( ‡ )

Src # 536: Classified as Class III on the basis of the Sung et al. (2009)Spitzer photometry. Cody et al. (2014) indicate, however, that the star has a mIR excess. This is based on the MIPS 240 μm flux (not reported by Sung et al. 2009), which is, however, strongly contaminated by a nearby YSO associated with ACIS source # 541.

(§)

Src # 713: The Chandra flare falls in the gap between the last two observations – EX was multiplied by 1.497 to approximatively correct for the missing exposure time.

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.
