Overview

The Coordinated Synoptic Investigation of NGC 2264 (CSI 2264) photometrically monitored the star-forming region NGC 2264 for 30+ days starting in December 2011. It constitutes a unique cooperative effort including 15 ground- and space- based telescopes. It was conceived of in the process of executing the Young Stellar Object Variability (YSOVAR) project (Morales-Calderon et al. 2011; L. Rebull 2014, submitted), and involves many of the same people and processing approach. These projects are exploring the variability properties of young stars in several young clusters at an unprecedented combination of cadence, photometric precision, and wavelength coverage, particularly in the infrared.

The CSI 2264 project performed photometric monitoring of young NGC 2264 cluster members using the Spitzer Infrared Array Camera (IRAC; Fazio et al. 2004) and the Convection, Rotation and Planetary Transits satellite (CoRoT; Baglin et al. 2006) simultaneously. Thirteen other telescopes monitored the region at different times concurrently with (or closely in time to) the primary Spitzer and CoRoT joint campaign. The CSI 2264 project is described in detail in Cody et al. (2014).

Table 3 consists of Spitzer light curves. Note that this table only contains light curves for objects that are very likely NGC 2264 members (using the criteria described in Cody et al. 2014), and that have at least 15 good data points in one of the IRAC bands. Only data from Warm Spitzer cycle 8 program 80040 (Dec. 2011- Jan. 2012) are provided. There are many rows for each object, because each object has many epochs of data. There are 13 columns in this table, as follows. Columns 11, 12, and 13 (the IRAC excess flag and the light curve types) are duplications of information found in our first table, but are repeated here to make it easy for users to, e.g., pull out all of the light curves of a specific type.
