The shifting fringes indicate a change in relative optical phase difference for -the two arms, which arises from the the difference in refractive indices of the +the two arms, which arises from the difference in refractive indices of the gas cell at low and atmospheric pressures $\Delta n$. According to Eq.(\ref{old3}), this difference is \begin{equation} \label{delta_n} |
