All Tables

Table 2: Slopes of the linear fits (b) and their errors ( $\Delta b$ ) of the different parameters in Fig. 2 with the central velocity dispersion. The left side ofthe table shows the values for the LDEGs, while the right side of the table, the values for the HDEGs. The last two columns show the result of a t-test to verify if the slopes of both subsamples of galaxies are different. In particular, the last column shows the probability that the slopesof HDEGs and LDEGs are different by chance.
Table 3: Fraction of light contributed by a burst of star formation with a metallicity [M/H]=+0.2 and a strength of 20% in mass, in a galaxy with an age 15.85 Gyr and a metallicity [M/H]=-0.38 for different ages of the burst.
Table 4: Slopes of the age-metallicity relation calculated in the Fe4383-H $\beta$ diagram for the three described distributions (see text), and for the LDEGs and HDEGs. The last two columns show the dispersion in age and metallicity for the different distributions and the subsamples of observed galaxies.
Table 1: Central ages and metallicities obtained in different index-index diagrams. The associated errors are indicated under the measurements. See Sect. 2 for more details.
