VizieR Online Data Catalog: SPLASH-SXDF multi-wavelength photometric catalog (Mehta+, 2018)
Abstract
For this photometric catalog, we use the optical Subaru Hyper-Suprime-Cam (HSC) imaging and the MIR warm-Spitzer data combined with archival optical and NIR imaging available from a variety of instruments and surveys. In this paper, we focus on a total area of 4.2deg2 centered at RAJ2000=02:18:00, DEJ2000=-5:00:00, matching the size of the available IRAC mosaics.
The catalog contains multi-wavelength photometry, photometric redshifts, and stellar masses. The catalog consists of ~1.16M objects detected on a multi-band detection image made by chi-squared summing the HSC-grzy, UDS-JHK, VIDEO-YHJKs, MUSUBI-u, CFHTLS-ugri to ensure selection of both red and blue objects. The photometry is measured on PSF-homogenized images to have a uniform typical seeing of 0.7" in all bands. HSC: The Hyper-Suprime-Cam Subaru Strategic Program (HSC-SSP; Aihara+ 2018PASJ...70S...4A) covers the SXDF in the grizy filters using the Hyper-Suprime-Cam on the Subaru 8m telescope on Maunakea, Hawaii. The Ultra-Deep layer of the HSC-SSP covers two fields, COSMOS and SXDF, in broadband and narrowband filters. The catalog contains the HSC-SSP optical data and Spitzer IRAC coverage obtained as part of the Spitzer Large Area with Hyper-Suprime-Cam (SPLASH) program (PID: 10042, PI: Capak, P. Capak et al. 2018, in preparation). Additional coverage from the Subaru SuprimeCam, UDS, VIDEO, MUSUBI and CFHTLS surveys is also included. The catalog also provides ancillary radio (Simpson+ 2006, J/MNRAS/372/741) and X-ray (Akiyama+ 2015PASJ...67...82A) data. Suprime-Cam: Additional optical coverage is available from the Subaru/XMM-Newton Deep Survey (SXDS; Furusawa+ 2008, J/ApJS/176/1), which includes BVRci'z' filters from the Subaru Suprime-Cam. UDS: The Ultra Deep Survey (UDS) includes NIR imaging in the JHK filters on the SXDF from the UKIRT Wide-Field Camera. We use the JHK mosaics from their Data Release 11 (http://www.nottingham.ac.uk/astronomy/UDS/data/dr11.html). VIDEO: The VISTA Deep Extragalactic Observations (VIDEO) survey (Jarvis+ 2013, III/334) covers the SXDF in ZYJHKs filters using the VISTA Infrared Camera (VIRCAM). MUSUBI: The ultra-deep CFHT u-band stack is provided by the program Megacam Ultra-deep Survey: U-Band Imaging (MUSUBI, W.-H. Wang et al. 2018, in preparation). The MUSUBI team acquired 41.8hr of u-band integration between 2012 and 2016, using MegaCam on CFHT. The image stack also includes 18.7hr of archived MegaCam u-band data within the SXDF. CFHTLS: The CFHT Legacy Survey (CFHTLS) also covers the SXDF in ugriz filters using MegaCam on CFHT, as part of its wide-field coverage. We use the stacked mosaics released in the Terapix CFHTLS T0007 release (http://www.cfht.hawaii.edu/Science/CFHTLS/). Photometric redshifts are available for all objects in the catalog computed using LePhare (Arnouts+ 1999MNRAS.310..540A ; Ilbert+ 2006A&A...457..841I). These photo-z's have been calibrated using spectroscopic data available from the variety of surveys and archival data in the literature. (1 data file).- Publication:
