$\begin{figure} \par\includegraphics[width=6.5cm,clip]{chauvin_fig1.eps} \end{figure}$ Figure 1: Composite image of brown dwarf 2M1207 and its GPCC in H (blue), $K_{\rm s}$ (green) and $L~\!'$ (red). The companion appears clearly distinguishable in comparison to the color of the brown dwarf 2M1207.

$\begin{figure} \par\includegraphics[width=7.9cm,clip]{chauvin_fig2.eps} \end{figure}$ Figure 2: Detection limits at $3\sigma$ achieved during our observations in J-band (dotted black line), H-band (dashed blue line), $K_{\rm s}$ -band (dashed-dotted green line) and $L~\!'$ -band (solid red line). The contrasts between 2M1207 and its GPCC are reported for H (filled triangle), $K_{\rm s}$ (filled box) and $L~\!'$ (filled circle) (the GPCC was not detected in J band).

$\begin{figure} \par\includegraphics[width=7.7cm,clip]{chauvin_fig3.eps} \end{figure}$ Figure 3: Color-color diagram (H-K vs. ${K}-{L}~\!'$ ) for 2M1207 (open circle) and its faint GPCC (point shown with error bars). The observed infrared photometry for late-M dwarfs (diamonds), L1-L4 dwarfs (crosses), L5-L9.5 dwarfs (asterisks) and T dwarfs (triangles) obtained by Leggett et al. (2002) and Stephens et al. (2001) are given for direct comparison.

$\begin{figure} \par\includegraphics[width=7.7cm,clip]{chauvin_fig4.eps} \end{figure}$ Figure 4: SH-band spectra of 2M1207 and its GPCC with the low resolution ( ${R}_{\lambda }=700$ ) grism of NACO, the 86 mas slit and the S54 camera (54 mas/pixel). The best adjustements were obtained with the template spectra of T513 (M8.5) for 2M1207, and SDSS0539 (L5) and 2M0310 (L9.5) for its GPCC.
