Index of the power law surface density profile. If Sigma0 is set to \Sigma_0, and SigmaSlope to \alpha, then the surface density profile is defined by:

\Sigma(r)=\Sigma_0r^{-\alpha}

SigmaSlope defaults to 0 (uniform surface density disk). The surface density decreases outwards if SigmaSlope is positive.
