Use of calibration data accumulated during every observations enable us to obtain the vast amount of solar system astronomical data. In turn, the total amount of data is quite large and all of the data need to be processed to see if the data is suitable for the scientific analysis. Therefore, we attempted to construct an automated ALMA data processing system and a new computer system specified for the conversion of ALMA calibration data into the scientific data. As a result, we succeeded to construct the automated data processing system that produces fits cube file and quick-look data of spectrum and 2-D brightness map, and to process the whole data of Neptune above Band 6. In addition, introducing a new SAS storage that enables both capacity, scalability and high-speed access succeeded to reduce the time required for calibration process to similar to 19-36% comparing with a standard NAS storage installed on 1 Gbps LAN network. A parallel data calibration system also decreased the processing time up to approximately 13%. In summary, we succeeded to draw a path for the comprehensive analysis of ALMA calibration data in a realistic machine-time.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1730023003","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-RR-17-009","subitem_description_type":"Other"}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20637/JAXA-RR-17-009/0003","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2216","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京農工大学科学博物館"},{"subitem_text_value":"東京農工大学"},{"subitem_text_value":"東京工業大学"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nature and Science Museum, Tokyo University of Agriculture and Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Agriculture and Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"飯野, 孝浩"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"並木, 美太郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山田, 崇貴"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iino, Takahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Namiki, Mitaro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamada, Takayoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-31"}],"displaytype":"detail","filename":"AA1730023003.pdf","filesize":[{"value":"4.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1730023003.pdf","url":"https://jaxa.repo.nii.ac.jp/record/1809/files/AA1730023003.pdf"},"version_id":"890a5fc5-0850-4d99-b3ed-b6b0d04545f8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Radio astronomy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ALMA","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Planetary atmosphere","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"ビッグデータ太陽系天文学の創成のためのALMAキャリブレーション観測データの悉皆的解析システムの検討と構築","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ビッグデータ太陽系天文学の創成のためのALMAキャリブレーション観測データの悉皆的解析システムの検討と構築"}]},"item_type_id":"3","owner":"1","path":["30","1401","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-03-19"},"publish_date":"2018-03-19","publish_status":"0","recid":"1809","relation_version_is_last":true,"title":["ビッグデータ太陽系天文学の創成のためのALMAキャリブレーション観測データの悉皆的解析システムの検討と構築"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:38:46.451335+00:00"}
