The reconstructed auroral luminous structure can provide useful information such as altitude profiles and vortex configuration. In order to obtain the absolute volume emission rate of the aurora distribution, it is essential to have the absolute sensitivity calibration of imaging by formulating the relation between pixel values and absolute brightness of corresponding direction of each pixel. The relation between pixel value and brightness is formulated and calculated from the absolute sensitivity calibration. We took the flat-field images of the integrating sphere calibration standard at National Institute of Polar Research using one camera system, which was installed at Merasjarvi (one of the ALIS observing site, ALIS is the acronym of Auroral Large Imaging System, which is a multi-station ground-based optical observing network). National Institute of Polar Research, Japan and Swedish Institute of Space Physics in Kiruna, Sweden have carried out collaborative observations for auroral tomography under ALIS. The sensitivity calibration result is applied to the reconstruction of volume emission rate distribution from the tomographic images observed by ALIS on March 1, 1998.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006280","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11397422","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Electrical Engineering, Kyoto University/National Institute of Polar Research/National Institute of Polar Research/Swedish Institute of Space Physics/Swedish Institute of Space Physics/Swedish Institute of Space Physics"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1999-09-01"}],"displaytype":"detail","filename":"KJ00000048020.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000048020","url":"https://nipr.repo.nii.ac.jp/record/6280/files/KJ00000048020.pdf"},"version_id":"0ea47b2e-5101-4b30-afb1-be7e39c9dcdc"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Camera calibration by an integrating sphere for the auroral tomography observation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Camera calibration by an integrating sphere for the auroral tomography observation"}]},"item_type_id":"1","owner":"4","path":["803"],"pubdate":{"attribute_name":"公開日","attribute_value":"1999-09-01"},"publish_date":"1999-09-01","publish_status":"0","recid":"6280","relation_version_is_last":true,"title":["Camera calibration by an integrating sphere for the auroral tomography observation"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:03:37.715864+00:00"}
