Samenvatting
We present a proper-motion study on models of the dwarf spheroidal
galaxy Sculptor, based on the predicted proper-motion accuracy of Gaia
measurements. Gaia will measure proper motions of several hundreds of
stars for a Sculptor-like system. Even with an uncertainty on the proper
motion of order 1.5 times the size of an individual proper-motion value
of ˜10 mas/century, we find that it is possible to recover
Sculptor's systemic proper motion at its distance of 79 kpc.
