$^1$ The $Q/I$ and $U/I$ values are {\it not} corrected for the pleochroism (see text).
%  \item[$^2$] 	
  $^2$ The reference polarisation degrees {and angles} are from \citet{Fossa07}. 
%  \item[$^3$]  
  $^3$ \citet{Fossa07} only reports measurements using the PMOS mode. For the $B$ and $V$ filters for which they report measurements in both IPOL and PMOS modes, one finds differences up to $(0.10\pm0.02)$\% and $(0.38\pm0.14)\deg$.
