Young Stellar Object VARiability (YSOVAR) GGD 12-15 Object Table

The YSOVAR (Young Stellar Object VARiability) Spitzer Space Telescope observing program obtained the first extensive mid-infrared (IRAC 3.6 and 4.5 micron) time series photometry of the Orion Nebula Cluster plus smaller fields in 11 other star-forming cores (AFGL 490, NGC 1333, Mon R2, GGD 12-15, NGC 2264, L1688, Serpens Main, Serpens South, IRAS 20050+2720, IC 1396A, and Ceph C). There are ~29,000 unique objects with light curves in either or both IRAC channels in the YSOVAR data set. YSOVAR is a sister project to the Coordinated Synoptic Investigation of NGC 2264 (CSI 2264; Cody et al. 2014). Initial YSOVAR results were described in Morales-Calderon et al. (2011). Rebull et al. (2014) describes the details of target selection, data reduction, and other conventions established for this project.

YSOVAR（Young Stellar Object VARiability，年轻恒星天体变异性）斯皮策空间望远镜观测项目首次获取了猎户座星云星团的大范围中红外（IRAC 3.6与4.5微米）时间序列测光数据，同时覆盖另外11个恒星形成核的小视场区域，涵盖AFGL 490、NGC 1333、Mon R2、GGD 12-15、NGC 2264、L1688、Serpens Main、Serpens South、IRAS 20050+2720、IC 1396A及Ceph C。YSOVAR数据集中共包含约29000个拥有单通道或双通道IRAC光变曲线的独特天体。YSOVAR与NGC 2264协调同步巡天项目（Coordinated Synoptic Investigation of NGC 2264，CSI 2264；Cody等，2014）为姊妹项目。YSOVAR的初步研究成果已由Morales-Calderon等人于2011年发表。Rebull等人2014年的研究则详细阐述了本项目的目标选取、数据归约及所采用的各项规范标准。本数据集及相关服务由IPAC下属的红外科学档案馆（Infrared Science Archive，IRSA）提供发布，而IPAC由加州理工学院根据与美国国家航空航天局（National Aeronautics and Space Administration，NASA）签订的合同运营。
