This program determines the four variables, Δx, Δy, θex, and log10 2α as the best point of the four variables from the starting set of 5 points of the four variables, where Δx is a difference between an empirical curve-of-growth and a theoretical curve-of-growth in the direction parallel to the abscissa and Δy is a difference between an empirical curve-of-growth and a theoretical curve-of-growth in the direction parallel to the ordinate. The objective function is taken to be the variance of lines in curve-of-growth in the direction parallel to the abscissa. This program is the combination between the program of the above downhill simplex method by Sprott and the program of the method 2 for curve-of-growth analysis by Yoshioka.\n　The effectiveness of this program was tested by comparing the results by this program with that by the program of the method 2 by Yoshioka. The data used for the comparison are those for 86 lines of Fe Ⅰ of HD187203. The following conclusions were drawn from the test.\n1) The best point is obtained for the tolerance values of the objective function between 0.001 to 0.00001.\n2) The best point depends on the starting set. But, the uncertainty due to the starting set is small in comparison with the one due to other cause in the curve-of-growth analysis.\n3) This program is an effective method for the curve-of-growth analysis. In comparison with the program of the method 2 by Yoshioka, this program reaches the four variables in quite short steps and in quite a short time."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉岡, 一男"},{"creatorName":"ヨシオカ, カズオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"9566","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 康夫"},{"creatorName":"コバヤシ, ヤスオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"9567","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshioka, Kazuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"9568","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Yasuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"9569","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-06-14"}],"displaytype":"detail","filename":"26-11.pdf","filesize":[{"value":"127.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"26-11","url":"https://ouj.repo.nii.ac.jp/record/7523/files/26-11.pdf"},"version_id":"a70262d4-b4f7-4626-a37e-54a1997b8ba9"}]},"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":"滑降シンプレックス法による成長曲線からの大気パラメータの決定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"滑降シンプレックス法による成長曲線からの大気パラメータの決定"},{"subitem_title":"The Determination of Atmospheric Parameters of Curve-of-Growth by the Downhill Simplex Method","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["436"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-06-14"},"publish_date":"2013-06-14","publish_status":"0","recid":"7523","relation_version_is_last":true,"title":["滑降シンプレックス法による成長曲線からの大気パラメータの決定"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T16:19:04.405479+00:00"}
