The numbers of spectral lines and their intensities are in accord with nonthermal-equilibrium cometary models. Rotational populations are derived from the observed spectral line intensities and excitation conditions are discussed. The ortho-para ratio was found to be 2.66 ± 0.13, corresponding to a nuclear-spin temperature of 32 K (+5 K, -2 K), possibly indicating that the observed water vapor originated from a low-temperature ice.\n          </jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381981471398433668","@type":"Researcher","foaf:name":[{"@value":"Michael J.
