Age gradients for LR-V, LR-B, and LR-B+LR-V spectral setups. In this plot, the age of the central ring is subtracted from the remaining age measurements. The scatter points are shifted slightly on the x-axis for better visualisation. Shaded red and blue areas show confidence levels for LR-V and LR-B setups. Dashed dark and light lines also represent 1σ and 2σ confidence levels, respectively, for the LR-B+LR-V spectral setup.
