\tablefoot{Wavelengths are in \AA\ and the Vega's monochromatic absolute fluxes in 
${10^{-10}~\rm erg~cm^{-2}~s^{-1}}~\AA^{-1}$.
2MASS effective wavelengths ($\lambda_{{\rm eff}}$), magnitudes and 
fluxes are from \citet{casagrande06}, where the latter has been modified by 
$-1.6, +1.5$ and $+0.3$ percent in $J,H$ and $K_{\rm S}$ band respectively as 
described in Sect.~\ref{tuning}. The TCS values are from 
\citet{alonso94:photometry}. For the TCS system $\mathcal{F}_{{\rm eff}}$ has 
been computed by shifting the value at the 2MASS effective wavelength (Fig.~\ref{f:absflx}). $\Delta(\%)$ is the percent decrease of the 
TCS $\mathcal{F}_{{\rm eff}}$ needed to match the 2MASS values.}
