All Tables

Table 1: ESO UVES archive data on the quasar Q 1101-264.
Table 2: Atomic data of the Fe II transitions^a, the sensitivity coefficients ${\cal Q}^b$ , and the isotope mass shift constants $k_{\rm MS}$ ^c. Estimated errors are given in parentheses.
Table 3: SIDAM analysis: optimized centroid positions of the Fe II lines in the main subcomponent and $\Delta \alpha /\alpha$ calculated with Eqs. (4) or (10).
Table 4: Fundamental photon noise limits $\tilde{\sigma}^{\rm lim}_{\Delta\alpha/\alpha}$ (in units of 10^-5) for Fe II pairs of lines ( $\lambda 1608/X$ ) from the $z_{\rm abs}$ = 1.839 system toward Q 1101-264. The exposure time $t_{\rm exp}$ and the total efficiency $\varepsilon _{\rm tot}$ are set to 3600 s and 0.15, respectively.
