1  Extracted employing ${{\mathit \pi}}{{\mathit K}}$ partial wave analysis from ESTABROOKS 1978 and ASTON 1988, Roy-Steiner equations and once subtracted forward dispersion relations.
2  Reanalysis of ESTABROOKS 1978 and ASTON 1988 satisfying Forward Dispersion Relations and using sequences of Pade approximants.
3  Reanalysis of data from ESTABROOKS 1978 and ASTON 1988 in the unitarized ChPT model.
