PMs of the stars in the field of view towards the different dSph galaxies in our sample. Members, defined as stars within 3σ of the mean measured PM and located in the expected region of the CMD, are shown in cyan. The green points correspond to stars that also fall in the CMD-selected box, but are not within 3σ of the systemic PM. Especially for Sculptor and Fornax, it is quite clear that there may be more members, but very likely, the large errors on the PMs of individual stars place them beyond the 3σ ellipse.
