VizieR Online Data Catalog: IR variability among YSOs in the Serpens South cluster (Wolk+, 2018)
Abstract
For this program, the field was observed using Spitzer from 2011 May through June (starting on about MJD 55700); these data are referred to as Young Stellar Object VARiability project (YSOVAR) data. The YSOVAR data were generated by a pair of pointings (one for [3.6] and one for [4.5]) with a field center of 18:30:04-02:02:05 (J2000; see Figure 1 and Rebull et al. 2014AJ....148...92R (Paper I); Figure 35). A fast cadence was used, meaning the observations were made in a series of 3.5 day cycles. Within each cycle, the time step between visits was incremented in 2 hr intervals from 4 to 16 hr. By using a linearly increasing time step, we were able to evenly sample, in Fourier space, a range of higher frequency (shorter timescale) photometric variability while minimizing the total amount of observing time necessary to sample these high frequencies and to minimize the period aliasing (see Paper I). The YSOVAR data consist of 82 observations of Serpens South over a 38 day period with a total exposure time of 14.7 hr.
