Combined metallicity distribution function of all clusters in substructure C/Gaia-Enceladus. We overlay the [Fe/H] distribution for all 34 532 stars with [Fe/H] from LAMOST LRS in our initial halo sample (containing 51 671 stars). We note that our selection of GE stars based on our clustering algorithm naturally does not suffer from contamination from the hot thick disc (red sequence). Error bars were computed assuming Poisson statistics.
