Comparison of different CMDs of the relevant RG sample of NGC 5897 by using B, V, and K photometry from P. B. Stetson et al. (2019) and M. F. Skrutskie et al. (2006), and Gaia G, G_BP, and G_RP photometry from Gaia Collaboration et al. (2021). When the photometric error bar of the data point is smaller than the size of the point, the error bar is shown by white inside the points. Our successful detections of solar-like oscillators are in color.
