Simulated tidal streams of NGC 5024 and Gaia CMD. Left panel: NGC 5024 and its mock stream shown in different projections of phase space. The dashed lines indicate the median values of δ, D, ﹩{\mu }_{\alpha }^{\ast }﹩, μ_δ as a function of α. Right panel: CMD using Gaia photometry. The color scale encodes the weight of each Gaia source according to the isochrone, where the PARSEC isochrone for NGC 5024 is overplotted as the green line.
