\par
$^a$~A negative value indicates that the fitted $^6$Li line is emission.
$^b$~This is the fitted shift necessary to match the observed profile, note that while the empirical and 1D profiles have a zero intrinsic shift the 3D profiles have +100\ms ~~and +300\ms\ convective shifts respectively. 
$^c$~Defined as the probability of obtaining a $\chi^2$ as high as the one observed.
$^d$~Fixed.
$^e$~Rotationally broadened by 1 \kms.
