The solid (white and green) curve and hatched (magenta and green) region represent our fiducial M(r) within 1σ confidence levels. This corresponds to the NFW best-fit to the lensing mass profile of U12 (white curve within magenta region) out to r_200,U (indicated by a vertical dashed line), and to the Caustic non parametric mass profile (green curve within light green region) beyond that radius. The dashed black curve represents the NFW best-fit solution obtained by the combined MAMPOSSt+Caustic analysis.
