By superposing the GCR density and density gradient observed in FDs following 45 interplanetary shocks (IP-shocks), each associated with an identified eruption on the Sun, we infer the average spatial distribution of GCRs behind IP-shocks. We find two distinct modulations of GCR density in FDs, one in the magnetic sheath and the other in the coronal mass ejection (CME) behind the sheath. The density modulation in the sheath is dominant in the western flank of the shock, while the modulation in the CME ejecta stands out in the eastern flank. This east-west asymmetry is more prominent in GMDN data responding to similar to 60 GV GCRs than in NM data responding to similar to 10 GV GCRs, because of the softer rigidity spectrum of the modulation in the CME ejecta than in the sheath. The geocentric solar ecliptic-y component of the density gradient, G(y), shows a negative (positive) enhancement in FDs caused by the eastern (western) eruptions, while G(z) shows a negative (positive) enhancement in FDs caused by the northern (southern) eruptions. This implies that the GCR density minimum is located behind the central flank of IP-shocks and propagating radially outward from the location of the solar eruption. We also confirmed that the average Gz changes its sign above and below the heliospheric current sheet, in accord with the prediction of the drift model for the large-scale GCR transport in the heliosphere.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"ASTROPHYSICAL JOURNAL. 825(2):100 (2016)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Munakata, K.","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.jaDeOUkh.html"},{"subitem_link_text":"Kato, C.","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.ONfFOUkh.html"}]},"item_6_link_67":{"attribute_name":"WoS","attribute_value_mlt":[{"subitem_link_text":"Web of Science","subitem_link_url":"http://gateway.isiknowledge.com/gateway/Gateway.cgi?&GWVersion=2&SrcAuth=ShinshuUniv&SrcApp=ShinshuUniv&DestLinkType=FullRecord&DestApp=WOS&KeyUT=000381940800018"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP PUBLISHING LTD"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.3847/0004-637X/825/2/100"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3847/0004-637X/825/2/100","subitem_relation_type_select":"DOI"}}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2016 The American Astronomical Society"}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0004-637X","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00553242","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kozai, M."}],"nameIdentifiers":[{"nameIdentifier":"105569","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Munakata, K."}],"nameIdentifiers":[{"nameIdentifier":"105570","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kato, C."}],"nameIdentifiers":[{"nameIdentifier":"105571","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kuwabara, T."}],"nameIdentifiers":[{"nameIdentifier":"105572","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Rockenbach, M."}],"nameIdentifiers":[{"nameIdentifier":"105573","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Dal, Lago  A."}],"nameIdentifiers":[{"nameIdentifier":"105574","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Schuch, N.
