Table 2 (J/ApJ/794/143/table2) estimates a NIR spectral type from SpeX observation of "L4.1:", in Sec. 4.1.5 of the text, under the erroneous ID "2MASS J14532589+1420418" (which doesn't seem to exist, but the implied position is within 1.2" of the correct 2MASS ID 2MASS J14532582+1420410 = SDSS J145325.89+142041.8), the authors consider this object a "strong candidate binary" of type L1+T6: "2MASS J1453+1420 was classified as an L1 in both the infrared (Kirkpatrick et al. 2010) and the optical (Schmidt et al. 2010), where it clearly shows excess flux in the J band and a dip in the H band. It is selected by 11 out of 12 spectral index combinations, and it is slightly blue with a J − Ks color of 1.18 ± 0.05 as compared to the median for the L1 spectral type 1.34 ± 0.19 (Schmidt et al. 2010). It is best fit by L1.1 ± 0.0 and T6.0 ± 1.1 components."
