On the definition of schemes for computing leading order isospin breaking corrections

We discuss an alternate scheme, or a ’line of constant physics’, which can be used when computing isospin breaking corrections to hadronic quantities.
We show that within a certain class of schemes one can separate the electromagnetic corrections from the strong isospin breaking corrections at leading order, meaning that within this class scheme-ambiguities are higher order effects.
