Young Stellar Object VARiability (YSOVAR) GGD 12-15 Light Curve 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（年轻恒星天体变异性，Young Stellar Object VARiability）斯皮策空间望远镜（Spitzer Space Telescope）观测项目，首次获取了猎户座星云星团的大规模中红外3.6与4.5微米波段（红外阵列相机，Infrared Array Camera，IRAC）时间序列测光数据，同时覆盖了另外11个恒星形成核心（AFGL 490、NGC 1333、麒麟座R2（Mon R2）、GGD 12-15、NGC 2264、L1688、巨蛇座主区（Serpens Main）、巨蛇座南区（Serpens South）、IRAS 20050+2720、IC 1396A及Ceph C）的小视场天区。YSOVAR数据集中共包含约2.9万个独特天体，这些天体在IRAC单通道或双通道测光中均拥有光变曲线。YSOVAR与NGC 2264协调同步观测计划（Coordinated Synoptic Investigation of NGC 2264，简称CSI 2264；Cody等，2014）为姊妹项目。YSOVAR的初步研究成果已由Morales-Calderon等人（2011年）发表。Rebull等人（2014年）详述了该项目的目标筛选、数据归约及项目制定的各项规范。
