Correlation plots between the metallicities (left) and ages (right) derived using the SIESTA code compared to the values from previous VISCACHA papers, where the ages and metallicities were derived by visually fitting isochrones to the VISCACHA CMDs (Paper VIII). The corresponding residual plots are displayed beneath each main plot. 1 and 2 sigma regions are shaded to provide a visual representation of the deviations in the correlation plot.
