cds-question@unistra.fryoung-stellar-objectspre-main-sequence-starsemission-line-starsprotostarsstellar-spectral-typesaccretionline-intensitiesThe past decade has seen a rise in the use of machine learning methods in the study of young stellar evolution. This trend has led to a growing need for a comprehensive database of young stellar objects (YSOs) that goes beyond survey-specific biases and can be employed for training, validating, and refining the physical interpretation of machine learning outcomes. We aim to review the literature focussed on the Orion star formation complex (OSFC) to compile a thorough catalogue of previously identified YSO candidates in the region, including the curation of observables relevant to probing their youth. Starting from the NASA/ADS database, the catalogue was assembled from more than 200 peer-reviewed publications targeting the OSFC. We collated data products relevant to the study of young stars into a dedicated catalogue, which was complemented with data from large photometric and spectroscopic surveys as well as the Strasbourg Astronomical Data Center. We also added significant value to the catalogue by homogeneously deriving YSO infrared classification labels, through a comprehensive curation of labels concerning the sources' multiplicity and through the derivation of probabilities of the candidate YSOs in our catalogue being contaminant extragalactic sources or giant stars.2025A&A...702A..63Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/702/A63CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/702/A63https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/702/A63http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/702/A63https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/702/A63https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/702/A63http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/702/A63GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/702/A63/tabled1 (Main table (tables D1, D3, D4, D9))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/702/A63/tabled1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/702/A63/tabled1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/702/A63/tabled1?GETtext/xml+votable180.050000true83.585291666666610.08955555555560.0055555555555555563/357 370 4/1338-1339 1342 1413 1424-1425 1427 1436-1437 1474-1475 1486 1504 5/5311 5324 5326-5327 5345-5347 5350-5351 5360 5362-5363 5374 5705 5707 5732-5733 5735 5753 5756-5757 5759 5844-5845 5888 5890 5938-5939 6020-6021 6023-6024 6027 6029-6030 6/21215 21235 21237-21240 21243 21285 21293 21295 21303 21352 21354-21355 21358 21376-21377 21379 21393-21396 21398-21399 21444 21446-21447 21458 21465-21467 21470 21488 21490 21492-21494 21500-21501 21503 22184 22186-22187 22190 22596-22597 22645 22647 22653 22816-22817 22819 22825 22827 22916-22917 22919 22936 22938-22939 22964-22965 22967 23008-23010 23017 23021 23023 23033-23035 23364-23365 23384-23385 23387-23390 23409 23412 23414-23415 23557-23559 23564 23566-23567 23576 23578-23579 23656 23659 23744-23746 23750 23792-23793 23795-23796 23798 23800-23802 24089-24091 24100 24103-24105 24107 24113-24115 24124 24128-24130 24132-24134 24136 24138-24140 24196-24197https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/702/A63?format=asciidefaultJ/A+A/702/A63/tabled1Main table (tables D1, D3, D4, D9)mir1[0/2] Total number of sed observations in the MIR range (4.0-5.0um)meta.numberintmir2[0/2] Total number of sed observations in the MIR range (5.0-6.0um)meta.numberintextgalLabel[-1/1]?
