Joint spectral and photometric fitting for star cluster G002 using BC03 models. Top panel: The observed spectrum (blue solid line) and photometry (blue points) overlaid with the best-fit model (gray dashed line). Horizontal error bars on photometric points represent the filter bandwidths, while vertical bars indicate photometric uncertainties. Bottom panel: The fitting residuals.
