\citet{Lop05}\smallskip\\ {\it Notes:}\\ 1: Apparently below the main sequence\\ 2: \citet{Mer08} fit a spectral type corresponding to a cooler temperature, with no extinction, and derive a lower luminosity that yields an unusually high disk-to-star luminosity ratio, $L_{\rm disk} / L_*$ ratio. Our results, involving moderate extinction, imply $L_{\rm disk} / L_* = 0.36$, closer to typical values among the Lupus 3 population.\\ 3: Unreliable fit probably due to veiling. See Table~\ref{tab:veiled}.\\ 4: Important K~excess in addition to veiling. No fit in \citet{Mer08}. \\ 5: Well known to apparently lie below the main sequence despite its M~5 spectral type. Variability reported by \citep{Com03}.\\ 7: Fit as M5 in \citet{Mer08}; close companion at 2''4, probably contaminating the photometry confusion.\\ 8: No fit in \citet{Mer08}.\\ 9: Fit much later than in \citet{Mer08} \\ 10: Highly variable.\\ 11: Candidate member in \citet{Nak00}. Variability suspected. A comparison with 2MASS photometry shows it to be fainter in J, H by 0.12 and 0.16~mag respectively, and brighter in Ks by 0.15~mag, in the observations of \citet{Nak00}.\\ 14: Variability suspected. A comparison with 2MASS photometry shows it to be brighter in J by 0.26~mag, and slightly fainter in HKs by 0.07~mag.\\ 15: Fitted by \citet{Mer08} as A0 with very high extinction, which seems unlikely because it sits in a low extinction region. It may be a background red giant instead.\\ 16: Strong K excess. No fit in \cite{Mer08}. \\ 17: Relatively blue spectral energy distribution, the fit seems reasonable. Hints of elongation; perhaps having a disk close to edge-on orientation.\\ 19: Sz 102 is a peculiar object with strong emission lines, veiling and underluminous.\\ 20: Very strong H$\alpha$ emission reported by \citet{Hug94}, possibly veiled. \\ 21: Our measured $I_{\rm C}$ is fainter than that in \citet{Hug94}, whereas the 2MASS $JHK_S$ magnitudes are brighter than those listed in that work by 0.4~mag. The source thus seems to be highly variable and our fit is likely to be affected by non-simultaneity of observations.\\ 22: Selected as possible member by \citet{Nak00} because of near-infrared excess.\\ 24: Variability at the $\sim$0.2~mag level in $JHK_S$ reported by \citet{Hug94}. Our $I_{\rm C}$ measurement is very similar to that of \citet{Hug94}. Probably variable.\\ 25: Possibly variable: 2MASS $J$ magnitude brighter than in \citet{Hug94} by $\sim$0.2~mag, but $H$ and $K_S$ almost identical. Our $I_{\rm C}$ measurement is $\sim$0.2~mag brighter than in \citet{Hug94}.\\ 26: K2 in \citet{Hug94}. The 2MASS $HK_S$ magnitudes are fainter than in \citet{Hug94} by $\sim$0.2~mag, but $J$ is very similar. Our measurement in $I_{\rm C}$ is 0.5~mag fainter than in \citet{Hug94}. Probably variable, affecting our fit.\\ 27: Moderately variable: the $R_{\rm C}$ and $I_{\rm C}$ in \citet{Com03} are 0.17~mag fainter than in the new WFI measurements, and the 2MASS $H$ and $K_S$ magnitudes are $\sim$0.1~mag brighter than the measurements in those bands given in \citet{Com03}.\\ 28: Photometry in $R_{\rm C}$ contaminated by a much bluer companion at 1''7, clearly detected in $R_{\rm C}$, much fainter in $I_{\rm C}$ and undetected in $z_{\rm WFI}$.\\ 29: Extended in the NE-SW direction in the $R_{\rm C}$ image. Hints of elongation in $I_{\rm C}$, point source in $z_{\rm WFI}$. It might possess an outflow.\\ 30: Very uncertain WFI photometry:marginal detection in $R_{\rm C}$ and $z_{\rm WFI}$, and very faint in $I_{\rm C}$.\\ 31: Slightly fainter companion at 2''.\\ 32: Undetected in $R_{\rm C}$ and faint in $I_{\rm C}$; uncertain fit at the WFI wavelengths.\\ 33: Close companion at 1''5 contaminating our photometry.\\ 34: Clearly elongated in the NW-SE direction in $R_{\rm C}$, hints of elongation also in $I_{\rm C}$ and $z_{\rm WFI}$. It might be scattered light by a close-to-edge-on disk.\\ 35: Slightly elongated in $R_{\rm C}$ and $I_{\rm C}$ in the NW-SE direction.\\ 36: High residual fit (over 0.2~mag rms).} \end{table}
