Detailed Description

Result of a three-point power-law fit \( y = C (x - x_c)^\beta \).

shift is \( s = x_3 - x_c \) measured from the point closest to \( x_c \), rather than \( x_c \) itself: \( s \) is the quantity the solve actually determines, it is positive by construction, and it stays well-conditioned when \( |x_c| \gg s \) – which is the whole point of the fit.
