Mocks of an old, metal-poor signal with contamination from Gaia Enceladus. The top, middle, and bottom rows correspond to the mock with 25%, 50%, and 75% of the stars coming from the old, metal-poor signal and the rest from contamination. In all cases, the total number of stars is N_S. The first column shows the outputted age-metallicity distribution from DirSFH and the second column shows this minus the observed Gaia Enceladus age-metallicity distribution. The contours show the observed GE distribution (blue) and the black shows the input age-metallicity distribution for the old-metal poor signal.
