Anisotropy profile for all halo stars (black line) and removing only GSE (red line) or Sgr (yellow line) members, and for the sample after accreted structures are removed (blue line). The lines correspond to the median values and the respective bands indicate the limits using 16th and 84th percentiles obtained with MC simulation.
