Simulated observations of Milky Way stars and galaxies in an LSST-like survey. (a) TRILEGAL simulated observation of Milky Way stars in a one field at = (45,40). (b) Simulated observation of galaxies in a 0.01 field based on [69] (A. Connolly, private communication). A Dotter isochrone for a 10 Gyr, [Fe/H] = stellar population at a distance of 300 kpc () is overplotted on both panels. For clarity, only 1/4 of sources in each panel are plotted. LSST-like photometric uncertainties have not been added to the simulated data.
