Log-slope of the DM density profile for Sculptor. The gray, green, and blue bands show the inferred DM density according to our models for the R, R_cz and R_c cases for a 3σ confidence level. The orange band indicates the log slope profile of a pure NFW with mass and concentration as expected from cosmological consideration (see text for details), as indicated in the legend. The vertical line shows the 3-D halflight radius as reference.
