An annual parallax of one of the bright maser features in this region was previously reported to be 0.189 ± 0.008 milliarcsecond (mas) using part of the same archival data as we used. However, we found that this maser feature is not the best to represent the annual parallax to S269 IRS 2w because the morphology is remarkably elongated in the east–west direction. For this study we have selected another maser feature showing simpler morphology. This makes the new annual parallax estimate more credible. Our newly obtained annual parallax is 0.247 ± 0.034 mas, corresponding to 4.05[+0.65 -0.49] kpc. This value is well consistent with the 3.7–3.8 kpc obtained using the kinematic distance estimates and photometric distance modulus. We considered two hypotheses for the water-maser spatial distribution, a bipolar outflow and an expanding ring, in a kinematic model fitting analysis with a radially expanding flow. At this stage, any conclusions about the systemic proper motion could not be drawn from the kinematic analysis. Alternatively, we evaluated the mean proper motion to be (0.39 ± 0.92, -1.27 ± 0.90) mas yr^-1 eastward and northward, respectively, from the obtained proper motions of the detected water-maser features. The newly obtained annual parallax and mean proper motion give the peculiar motion of S269 IRS 2w to be (U_s, V_s, W_s) of (8 ± 6, -21 ± 17, 1 ± 18) km s^-1.", "subitem_description_type": "Other"}]}, "item_6_full_name_3": {"attribute_name": "別言語の著者", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "122924", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "朝木, 義晴"}]}, {"nameIdentifiers": [{"nameIdentifier": "122925", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "今井, 裕"}]}]}, "item_6_publisher_23": {"attribute_name": "公開者・出版者", "attribute_value_mlt": [{"subitem_publisher": "American Astronomical Society"}, {"subitem_publisher": "IOP Publishing"}]}, "item_6_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isIdenticalTo", "subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1088/0004-637X/787/1/54", "subitem_relation_type_select": "DOI"}}]}, "item_6_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "American Astronomical Society"}]}, "item_6_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0004-6256", "subitem_source_identifier_type": "ISSN"}]}, "item_6_source_id_9": {"attribute_name": "NII書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00552749", "subitem_source_identifier_type": "NCID"}]}, "item_6_subject_15": {"attribute_name": "NDC", "attribute_value_mlt": [{"subitem_subject": "440", "subitem_subject_scheme": "NDC"}]}, "item_6_text_30": {"attribute_name": "NIIタイプ", "attribute_value_mlt": [{"subitem_text_value": "Journal Article"}]}, "item_6_version_type_14": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "ASAKI, Yoshiharu"}], "nameIdentifiers": [{"nameIdentifier": "122920", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "IMAI, Hiroshi"}], "nameIdentifiers": [{"nameIdentifier": "122921", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SOBOLEV, A.
