$^\dagger$ JD~=~BJD~$-$~2~453~000.
$^\natural$ $\sigma_{\rm O-C}$ is the weighted rms   of the residuals (weighted by $1/\epsilon^{\rm 2}$, where $\epsilon$ is the 
O$-$C uncertainty). 
$^\star$ $\chi^{\rm 2}_{\rm red}$~=~$\chi^{\rm 2}/\nu$ where $\nu$ is the number of degrees of freedom (here $\nu$~=~$N-6$). 
$^\ddagger$ Post-fit $\chi^{\rm 2}$ probability computed with $\nu$~=~$N-6$.
