Phantom dark matter in Draco. The blue, green, and red curves assume a stellar mass-to-light ratio of 1, 3, and 5 M_⊙/L_⊙, respectively. The solid curves are for a flattened baryonic component and the dashed curves are for a spherical distribution. The panels in the upper row show the distribution of the phantom dark matter in units of 10⁷ M_⊙ kpc⁻³ along the line of sight from the Sun (left panel), along the major (positive vertical axis, middle panel) and minor axis (negative vertical axis, middle panel) of the ellipsoidal distribution on the plane of the sky as observed from the Sun, and the distribution along the line of sight from the Milky Way centre (right panel). The panels in the middle and bottom rows show the value of and the magnitude of the internal Newtonian gravitational acceleration, respectively. In the middle and bottom rows the panels are arranged from left to right as in the top panels. The horizontal black lines in the bottom panels show the magnitude of the external field, which is almost constant across the dwarf galaxy. In all the panels, the vertical black solid lines locate the centre of the dwarf. Left and right panels: the Milky Way is at large positive radii.
