cds-question@unistra.frh-ii-regionsyoung-stellar-objectsinfrared-sourcesThe optically bright, extended HII region Sh2-252 is a part of the Gemini OB1 association. This region is mainly composed of two small clusters NGC 2175s and Teu 136 and four CHII regions namely A, B, C and E. In this paper, an extensive survey of the star-forming complex Sh2-252 has been undertaken with an aim to explore its hidden young stellar population, its characteristics, spatial distribution, morphology of the region and finally to understand the star formation scenario of the complex for the first time. Spitzer-IRAC, MIPS photometry (3.6-24um) are combined with 2MASS-NIR and optical data sets to identify and classify the YSOs by their IR excess emission from their circumstellar material. From the well-fit models for each source derived from the SED fitting tool, we calculated the {chi}^2^ weighted model parameters such as the stellar mass (M*), temperature (T*), stellar age (t*), mass of the disc (Mdisc), disc accretion rate (dMdisc/dt), envelope accretion rate (dMenv/dt) presented in table1.dat.2013MNRAS.432.3445Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/432/3445CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/432/3445https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/432/3445http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/432/3445https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/432/3445https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/432/3445http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/432/3445GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/432/3445/table1 (Physical parameters of YSOs from SED fits)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/3445/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/3445/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/3445/table1?GETtext/xml+votable180.050000true92.2424380620.391663060.0055555555555555566/23980-23982https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/432/3445?format=asciiInfrareddefaultJ/MNRAS/432/3445/table1Physical parameters of YSOs from SED fitsrecnoRecord number assigned by the VizieR team.
