Notes. 

(a)

Detection significance.

(b)

MOS-equivalent count rates in the 0.3 − 7.8 keV band.

(c)

Identifications labelled DM, LOri and Lori-SOC are from Dolan & Mathieu (1999), Barrado y Navascués et al. (2004), and Bouy et al. (2009), respectively. 2MASS J05340691+1001005 (LOX 1) and J05351974+0947476 (LOX 99) are stars X2 and X4 from Stone & Taam (1985). The two stars with TYC identification are stars b and f in Murdin & Penston (1977).

(d)

Member = previously known members and candidates, NM = previously known non-members, New? = possible new candidates. For known non-members we also indicate in parenthesis the reason for membership exclusion.

(e)

This star has a fainter visual companion (2MASS J05340664+1001034, J = 13.10 mag) at a distance of  ~5 arcsec, which however falls outside our identification radius (offset = 4.2 arcsec).
