Notes. 

(a)

Effective temperatures were converted with the temperature scale for pre-main sequence stars given in Luhman et al. (2003) for spectral types later than M0. The effective temperatures of earlier spectral types are from Schmidt-Kaler (1982). Uncertainties are from Teff at the SpT uncertainty limits.

(b)

Results from comparing Teff and L ∗  with the models of Siess et al. (2000).

(c)

Positive values indicate emission lines, negative values indicate Brγ in absorption. Upper limits refer to the minimum equivalent widths of an emission line at λBrγ that can be detected with 3σ significance. Whenever possible, equivalent widths were extracted from the rK-corrected spectra. Values from targets without rKare in parantheses. These can be regarded as lower limits to the equivalent width of the Brγ line and no accretion luminosities or mass accretion rates were derived.

(d)

The disk probability is the result of the integration described in Sect. A.1.2. This does not exclude the possibility of “filled-up” absorption lines where emission and absorption cancel each other.

(e)

The spectral features allow us to assign a spectral type, but the spectral fitting routine was unable to match the overall continuum shape of this target, in particular for a strong increase at λ > 24   000 Å.

(f)

These extinction values were derived from our spectral fitting instead of photometry, since our photometric information was incomplete.
