    "abstract": "An analysis of $K^+$-d total cross section data is undertaken to explore\npossible effects of the recently observed resonance in the S=+1 hadronic system\nwith mass around 1.55 GeV. It is found that a structure corresponding to the\nresonance is visible in the data. The width consistent with the observed\ndeviation from background is found to be $0.9\\pm 0.3$ MeV and the mass is\n$1.559\\pm 0.003$ GeV/c$^2$ for spin-parity $\\h^+$ and $1.547\\pm0.002$\\\nGeV/c$^2$ for $\\h^-$. The errors are one standard deviation and statistical\nonly.\n  \\",
