Table 2:
Identification of Chandra X-ray sources with optical
or infrared counterparts in the CrA star-forming
region. Columns 2-4 provide information on counterparts to the
X-ray sources in the optical DSS images, the 2MASS images,
and the Spitzer images: "y'' means that a counterpart exists, "n''
means that no counterpart can be seen. Column 5 gives the SED class
derived from the Spitzer photometry, and the last 3 columns give
names, spectral types, and stellar bolometric luminosities of the stars
collected from
Casey et al. (1998); Olofsson et al. (1999); Walter et al. (1997); Neuhäuser et al. (2000); Wilking et al. (1992); Prato et al. (2003); Nisini et al. (2005);
additional references are given in the discussion of the individual
objects in Sects. 3 and 4.
