Δ_{CF606W,F814W,F322W2} vs. Δ_Fg06w,F814w ChMs for M dwarfs with 20.5 < m_F814W < 24.00 mag (left panels) and m_F814W vs. C_{F606W,F814W,F322W2} pseudo-CMD of M dwarfs from Marino et al. (2024a, right panel). The probable 1P, 2P_A, 2P_B, 2P_C, and 2P_D stars, selected from the ChM, are coloured crimson, orange, green, cyan, and blue, respectively. The inset in the right panel is a zoomed-in view of the m_F814W vs. C_{F606W,F814W,F322W2} pseudo-CMD around the MS region, where the five stellar populations are more clearly distinguishable. The fiducial lines of the five stellar populations are represented with solid coloured lines, while the dotted lines represent the corresponding fiducial lines for equal-luminosity binaries.
