Fits to the photometric SEDs (and spectroscopic data; not shown) of the four ring sections (see locations in Fig. 2). We imposed an extinction of the young stellar population to be ﹩A_{V}\geq 3﹩ mag. Observational data points are shown as redopen circles with their corresponding 1 σ uncertainties. The SED of the young stellar population is represented by a green line, the intermediate‐age population by an orange line, and the total (sum) fitted SED by a blue line. The green squares, orange triangles, and blue triangles are the model photometric points (SB99 SEDs convolved with HST‐filter throughputs) of the best fit for each population, respectively.
