YSOVAR Light Curve Catalog Definitions


The YSOVAR (Young Stellar Object VARiability) Spitzer Space Telescope observing program obtained the first extensive mid-infrared (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 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; R14) describes the details of target selection, data reduction, and other conventions established for this project.
