Observed ﹩V-{{I}_{C}},V﹩ color–magnitude diagram of NGC 7129 with the Hα emission sources shown as solid red circles, X-ray sources as green crosses, and other sources from the KPNO T2KA survey as gray points. The zero age main sequence (ZAMS) of Siess et al. (2000) is overplotted assuming the dwarf colors presented by Kenyon & Hartmann (1995), derived from those of Bessell & Brett (1988) and a distance of 1150 pc (Straižys et al. 2014).
