  In the framework of the STREGA (STRucture and Evolution of the GAlaxy)
survey, two fields around the globular cluster Pal 12 were observed with the
aim of detecting the possible presence of streams and/or an extended halo. The
adopted stellar tracers are the Main Sequence, Turn-off and Red Giant Branch
stars. We discuss the lumi- nosity function and the star counts in the observed
region covering about 2 tidal radii, confirming that Pal 12 appears to be
embedded in the Sagittarius Stream. Adopting an original approach to separate
cluster and field stars, we do not find any evidence of sig- nificant
extra-tidal Pal 12 stellar populations. The presence of the Sagittarius stream
seems to have mimicked a larger tidal radius in previous studies. Indeed,
adopting a King model, a redetermination of this value gives r_T = 0.22 +- 0.1
deg.
