Table 2:

Ages and metallicities of the central 2'' of NGC 205.
\begin{displaymath}{ \begin{tabular}{lccccc} \hline \hline\\ [-3.2mm] SSP & $\ch... ...30\pm0.03$ & $-0.67\pm0.04$ & -- & -- \\ \hline \end{tabular}}\end{displaymath}
(1) The first digit (1 or 2) refers to the number of the SSP component described on the line, while the second specifies a single- or two-burst fit. (2) MC in the $\chi ^2$ column indicates that the parameters are derived from 1000 Monte Carlo simulations. The values are the means of the results of the simulaitons and the errors are their standard deviation. MC1 is the Monte Carlo result of the SSP (i.e. 1-burst) analysis of the composite 2-burst model derived above, and assuming the same noise as in the observed spectrum. (3) and (4): $f_{\rm mass}$ is the fraction of the total mass in the burst, and $f_{\rm light}$ the corresponding light fraction.
