Left panel: spatial distribution of the Pleiades members according to Hunt & Reffert (2024, purple dots) and Cantat-Gaudin et al. (2018, blue dots). The symbol size scales with the G magnitude. The green diamonds mark the K2 variable stars in Rebull et al. (2016) that are not members according to either Hunt & Reffert (2024) or Cantat-Gaudin et al. (2018). Red dots represent the stars observed with LAMOST MRS. The meaning of the symbols is also indicated in the legend. Middle panel: color–magnitude diagram of the same sources. Right panel: proper motion diagram of all the Gaia DR3 sources with G ≤ 15 mag (small grey dots) in the field of the Pleiades (center coordinates RA(2000) = 03^h46^m, Dec(2000) = +24°06′, radius 4°). The Pleiades members are highlighted with the same symbols as in the other panels. The cyan asterisk denotes the average proper motion of the cluster according to Hunt & Reffert (2024) and the cyan ellipse is the 3σ contour.
