The annotations on the original plot give and . Use those displayed values rather than fitting the linear-axis curve as though its slope were a logarithmic exponent. Exponent inference from a magnetic data collapse identifies .
Therefore
These estimates inherit both the empirical collapse exponents and the assumed scaling identities, including three-dimensional hyperscaling. They are not independent high-precision measurements of five exponents. In particular, the small difference defining and the subtraction defining amplify uncertainties. No experimental curve or source image is reproduced.
