VizieR Online Data Catalog: YSOVAR: infrared photometry in NGC 1333 (Rebull+, 2015)

We present the Young Stellar Object VARiability (YSOVAR) data for NGC1333. There are 701 objects (see Table1) with mid-infrared light curves in one or both warm Spitzer bands. All YSOVAR Spitzer light curve tabular data are available via the YSOVAR data delivery to the Infrared Science Archive (IRSA; http://irsa.ipac.caltech.edu/frontpage/). The sky observed by the two IRAC channels (3.6 and 4.5μm, or IRAC-1 and -2) fields of view is slightly offset with the central ~10'*10' region, centered on 03:29:06+31:19:30, covered by both channels. The observations were obtained under program ID61026, between 2011 October 10 and November 14 (~35 days).

Near-infrared observations were obtained using the Peters Automated Infrared Imaging Telescope (PAIRITEL), which is an automated 1.3m telescope. PAIRITEL was located at the Whipple Observatory at Mt. Hopkins, Arizona; the same telescope and camera used for the northern part of 2MASS, PAIRITEL acquired simultaneous J, H, and K_s images. The observations of NGC1333 were obtained over 24 epochs from 2010 October 7 to 2012 November 19.

We compiled additional photometry from several different sources. Early in the Spitzer mission, NGC1333 was observed by both the guaranteed time observations (GTOs) and the Cores-to-Disks (c2d) Legacy program (Evans et al. 2009, cat. J/ApJS/181/321), with both IRAC and the Multiband Imaging Photometer for Spitzer (MIPS).

NGC1333 was covered in the Two-Micron All Sky Survey (2MASS; see cat II/246) and was also located in a field targeted by the long exposure 6X 2MASS program (see cat II/281). As described in Rebull 2015 (cat. J/AJ/150/17), we included these main 2MASS catalog and deeper 6X catalog near-infrared JHK_s data into our database. We also include the ~30 deep JH space-based measurements from Greissl et al. (2007AJ....133.1321G).

Chandra X-ray Observatory Advanced CCD Imaging Spectrometer for wide-field imaging (ACIS-I) observations of NGC1333 were first reported in Getman et al. 2002 (cat. J/ApJ/575/354) and then Winston et al. 2010 (cat. J/AJ/140/266). There are three pointings in NGC1333, with obsids 642, 6436, and 6437, with a total exposure time of 119.3ks.

NGC1333 was observed in several optical bands from Subaru and the Canada-France-Hawaii Telescope (CFHT), and we obtained these data from the public archives. Optical data from both telescopes cover the full extent of the region monitored for YSOVAR. NGC1333 was observed in the i' and z' bands with the Suprime-Cam wide-field camera on Subaru on 2006 November 18. A total of 1 short exposure (10s) and 60 dithered long exposures (60s) were obtained in each filter as part of the SONYC project (Scholz et al. 2012, cat. J/ApJ/744/6). NGC1333 was observed in the ugri filters at several epochs (2005 Sep 27 with g filter; 2008 Dec 21, 2009 Mar 24, 2009 Mar 26, and 2009 Sep 21 with i filter; 2005 Sep 27 with r filter; 2005 Sep 27, 2005 Dec 23, and 2006 Feb 28 with u filter) with the MegaCam wide-field camera mounted on the CFHT as part of the DANCE survey (Bouy et al. 2013A&A...554A.101B). The individual CFHT images were retrieved from the public archives maintained at the Canadian Astronomy Data Centre.

Single-valued measurements (such as the single-epoch optical photometry) or metrics (such as the SED slope and class, or mean from the light curve, etc.) for all of the objects with light curves are collected in Table1.
