Caption: Figure 5.

Ratio of DM to stellar mass as a function of radius for the FDM halo models, compared with their CDM halo counterparts. The black bar at the bottom indicates the spatial extent of the kinematic data. All four models show Dragonfly 44 to be DM-dominated (﹩{M}_{\mathrm{DM}}/{M}_{* }\gt 1﹩) down to ∼0.1 kpc.
