Impact parameters from each study along with the gradient of the slope fit to the literature data (y) and the simulation slopes resulting from the impact parameter degeneracy (y′).

Notes. By “input” we denote to the impact parameter value used to create synthetic light curves of a flat spectrum, and y′ is the slope caused by fitting these synthetic light curves with the deviating impact parameter.
