We recover the main sequence and main sequence turn-off of the Triangulum-Andromeda structure recently found by Majewski and collaborators at a heliocentric distance of ~20 kpc. The survey also reveals another less populated main sequence at fainter magnitudes that could correspond to a more distant stellar structure at ~28 kpc. Both structures are smoothly distributed over the ~76 sq. deg. covered by the survey although ","authors_text":"(2) Observatoire de Strasbourg, (3) IoA, Cambridge), Heidelberg, Mike Irwin (3) ((1) MPIA, Nicolas F.
