Abstract
In this proceeding we perform a separate chiral and continuum extrapolation of the scattering length for the $\pi-K$ scattering in the maximal isospin channel $I_3=\frac{3}{2}$. In order to verify our approach, we extrapolate separately the meson parameters (pion mass and decay constants, eta mass) to the physical point. Our approach uses a minimal set of input parameters in the extrapolation and is an alternative to the combined chiral and continuum extrapolation. We compare the extrapolated scattering lengths with our already published results.
