Description:
Table 2 contains the heliocentric radial velocity data versus
Heliocentric Julian Day for six X-ray selected double-lined
spectroscopic binaries in Orion. Of these, the four systems RXJ
0529.4+0041, RXJ 0530.7-0434, RXJ 0532.1-0732, and RXJ 0541.4-0324 are
pre-main sequence systems.
Table 3 contains the radial velocity data for the third components of
the spectroscopic systems RXJ 0441.0-0839, RXJ 0529.4+0041, and RXJ
0532.1-0732
