Notes.

^(a)

Based on optical spectra from Cruz et al. (2009). As also explained in Kirkpatrick (2005), the β and γ appended to the L subtypes indicate intermediate- and very low-gravity spectra, respectively.

^(b)

2MASS photometry (Skrutskie et al. 2006).

^(c)

WISE photometry.

^(d)

Spitzer photometry.

^(e)

W4 = 8.42±0.26 mag. Other sources are not detected in the W4 filter.

^(f)

Spitzer [24] = 10.78±0.15 mag.

^(g)

Spitzer [24] = 10.55±0.10 mag.
