Table 1: Journal of observations.
Table 3: Frequencies and amplitude signal/noise ratios obtained for each uvby filter.
Table 4: Results from the Fourier analysis applied to the uvby data collected in the year 2000.
Table 6: uvby $\beta$ indices obtained for V2109 Cyg and comparison stars. The pairs below the star names are the number of points collected for each object in uvby and $\beta$ , respectively. For comparison, the values available from the bibliography are listed in the bottom part. The values listed for the variable are "mean values'' based on the normal points along the cycle (Table 7). For this star, the comparison with the earlier available Strömgren indices (bottom part) must be made at phase 0.15 where the indices are, according to Table 7: $V=7\hbox{$.\!\!^{\rm m}$ }438$ , $b-y=0\hbox{$.\!\!^{\rm m}$ }214$ , $m_1=0\hbox{$.\!\!^{\rm m}$ }171$ and $c_1=0\hbox{$.\!\!^{\rm m}$ }874$ .
Table 8: Reddening and derived physical parameters for V2109 Cyg.
Table 9: Observed metallicity index variation for V2109 Cyg together with some known high amplitude $\delta$ Sct-type variables from Rodríguez et al. (1991). $\Delta$ $\delta$ m₁^* means variation of the $\delta$ m₁ parameter per each 0 $.\!\!^{\rm m}$ 1 variation in the $\beta$ index.
Table 10: Elemental abundances for V2109 Cyg. The solar abundances are taken from Grevesse et al. (1996). N is the number of lines included in the calculation.
