An improved analysis of the Michelson--Morley-type experiment by Antonini et al. [Phys. Rev. A. 71, 050101 (2005)] yields the Robertson--Mansouri--Sexl theory parameter combination $\ensuremath{\beta}\ensuremath{-}\ensuremath{\delta}\ensuremath{-}1∕2=(\ensuremath{-}0.6\ifmmode\pm\else\textpm\fi{}2.1\ifmmode\pm\else\textpm\fi{}1.2)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}10}$ and the standard model extension theory parameter ${({\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\kappa}}}_{e\ensuremath{-}})}^{ZZ}=(\ensuremath{-}2.9\ifmmode\pm\else\textpm\fi{}2.2)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}14}$.
