\caption {\label{Tab:radius}Radii of M~giants in binary systems derived from the Stefan-Boltzmann
law ($R_{\rm SB}$) and from high-angular resolution measurements ($R_{\rm HR}$).
 The labels
``UD'' and ``LD'' refer to uniform discs or limb-darkened discs, respectively.
Luminosities are derived from the
Hipparcos parallaxes $\varpi$, from the 2MASS $K$~magnitudes and bolometric corrections
$BC_K$ derived from the ($V-K$ , $BC_K$) analytical relation from 
\citet{Bessell-Wood-84}, which is in good agreement with
the more recent calibration of \citet{Bessell-98}. The Johnson $V_J$
magnitude from the Hipparcos catalogue has been used. Effective
temperatures are derived from the $V_J-K$ indices using the ``bcd'' calibration of \citet{Bessell-98}.

$^a$ From Richichi et~al. (2005, CHARM2) \nocite{Richichi-2005}, 
\citet{Verhoelst-2007} and \citet{Richichi-2005b};  
$^b$ from \citet{Richichi-2005b}; 
$^c$ these values are taken from \citet{Verhoelst-2007}; the
calibrations used for the other stars, and based on the $V-K$~colour
index, cannot be used for HD~41~511 because the $V$~band is
contaminated by light from the A-type companion.
