Most of the researches based on the old star catalogues were manuscript published in Europe and from Arabic/Islam. However, the old star catalogues published in East Asia did not get attention. Therefore, among the East Asian star catalogues we focus on a particular catalogue recorded in a Korean almanac. Its catalogue contains 277 stars that are positioned in a region within 10{deg} of the ecliptic plane. The stars in the catalogue were identified using the modern Hipparcos catalogue (Cat. I/239). We identified 274 among 277 stars, which is a rate of 98.9 percent. The catalogue records the epoch of the stars' positions as AD 1396.0. However, by using all of the identified stars we found that the initial epoch of the catalogue is AD 1363.1+/-3.2. In conclusion, the star catalogue was compiled and edited from various older star catalogues. We assume a correlation with the Almagest by Ptolemaios. This study presents newly analysed results from the historically important astronomical data discovered in East Asia. Therefore, this star catalogue will become important data for comparison with the star catalogues published in Europe and from Arabic/Islam.</description><source format="bibcode">2015MNRAS.454.1086J</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/454/1086</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/I/239">I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/454/1086</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/454/1086</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/454/1086</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/454/1086</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/454/1086</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/454/1086</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/MNRAS/454/1086/tableb (The COSC's catalogue data)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/454/1086/tableb?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/454/1086/tableb?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/454/1086/tableb?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>7.7595</ra><dec>7.3616</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/116 119 137 146 179 195 371 382 425 428 461 463 472 485 592 594 614 627 653 678 688-689 705 712 776 1033 1038 1061 1071 1074 1154 1158 1164 4181 4190 4201 4337 4359 4365 4419 4444 4528 4576 4632 4679 4686 4698 4702 4722 4748 4770 4802 4868 4873 6166 6176 6183 6196 6203 6219 6296 6340 17086 17358 17368 17395 17398 17909 18165-18166 18183 18205 18213 18278 18308 18313 18373 18417 18464 18494 18498 18527 18547 18572 18591 18602 18612 18651 18688 18697 18702 18797 18804 18893 18979 19508 19525 19534 19585 22518 23517-23518 23538 23540 23547 23551 23773 23853 23876 23922 23944 23963 23979 23993-23994 24005 24037 24100 24102 24129 24135 24151 24172 24178 24187 24206 24209 24222 24225 24260 24278 24290 24328 24332-24333 24352 24363 24420 24481 25437 25609 25659 25663 25674 25711 25742 25768 25804 25817 25834 25853 25858 25995 26142 26257 26276 26320 26974 26978 26981 27028 27102 27118 27130-27131 27498 27506 27531 27546 27570-27571 27599 27603 27698 27709 27781 27795 27815 27822 28777 28784 28841 28853 28934 28944 28968 28980 29001 29005 29021 29023-29024 29089 29208 29213 29236 29254 29256 29258 29286 29353 29359 29712 29732 42910 42932 42948 42956 42979 44248 44289 44305-44306 44351 44360 44366-44367 44369 44371 44375 44378 44399 44451 44492 44500 44515 44709 44762 44774 44794 44797 44807 44833 44841 44876 44901 47989-47990 47996-47997 48038 48051 48088 48100 48104 48349 48358 48516-48517 48526 48535 48545 48553 48567 48570 48578 48588-48589 48599 48606 48624 48637 48746 48754 48756 48760 48804 48829 48851 48885 48889 48936 48957</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/454/1086?format=ascii</footprint></coverage><tableset><schema><name>default</name><table><name>J/MNRAS/454/1086/table1</name><description>The summary of about 15 constellations included in COSC</description><column><name>recno</name><description>Record number assigned by the VizieR team.
