DESCRIPTION:Speakers: Amandine Doliva-Dolinsky (Observatoire Astronomique 
 de Strasbourg)\nThe large uncertainties on the measurement of the mass of 
 galaxies is an important issue in modern astrophysics. For both the MW and
  M31\, thanks to the gas rotation curve\, the mass of the inner part of th
 e haloes is well constrained. For the outer part of the haloes\, we must t
 urn to satellites galaxies as tracers. But\, to use dwarf galaxies as such
 \, it is absolutely crucial to determine the dwarf galaxy detection limits
  so they can be accurately modeled into the dwarf galaxy system models. I 
 will present the first such effort to characterize fully the dwarf galaxy 
 system of the Andromeda galaxy\, based on the PAndAS photometric mapping. 
 As expected\, the detection limits are a strong function of the size\, lum
 inosity and the location of a dwarf galaxy in the survey. I will then pres
 ent the impact of such completeness on the determination of M31 mass.\n\nh
