The Hβ index vs. the SSP age derived from the two spectra at r = 2.″5 (left) and r = 2.″5 (left). The measurement of the strong age-indicator Hβ appears to be a strong predictor of the age, which suggests the age we derived is a direct result of the measured spectra and not a random modeling result.
