r₂ vs r₂–i₂ and r₂ vs r₂–Y CMD plots are shown in this figure. The grey dots are the complete HSC+UKIDSS 802 100 sources, the red dots are the non-member population, and the blue dots are the candidate members of the training set. Isochrones of age 0.5, 1, 2, 4, 10, and 25 Myr from Baraffe et al. (2015) are plotted after correcting for visual extinction of A_V = 1 mag and distance of 917 pc. Reddening laws of Wang & Chen (2019) are used to correct the extinction of isochrones. The length and direction of the reddening vector of A_V = 2 mag is shown as the black arrow. Details regarding the use of the extinction and distance values are explained in Section 6.1.
