VizieR Online Data Catalog: SHELA survey. IV. Multiwavelength phot. cat. (Leung+, 2023)

We observed the Spitzer-HETDEX Exploratory Large-Area (SHELA) field using the DECam imager on the Blanco 4m telescope at CTIO in the u, g, r, i, and z filters. New data were obtained over three nights in the 2019B semester (PI: Papovich; NOAO PID: 2019B-0080). Our program also includes data obtained over five nights in the 2013B semester presented in Wold+ (2019, J/ApJS/240/5 ; Paper II). The complete program consists of eight slightly overlapping pointings covering a total area of 23deg².

We supplement our data with archival DECam imaging data within the footprint of the SHELA field in the ugriz bands. We also include archival data in the Y band, which was not observed by our proprietary program. All such archival data available through the NOIRLab Astro Data Archive released prior to 2021 March 3 were included for this catalog.

We incorporate multiwavelength imaging data from surveys overlapping with the SHELA field. This includes NEWFIRM Ks-band images from the NEWFIRM HETDEX Survey (NHS; Stevans+ 2021ApJ...921...58S) and mid-infrared mosaics in 3.6 and 4.5um with Spitzer/IRAC presented in Papovich+ (2016ApJS..224...28P). We also make use of publicly available data from PDR3 of HSC-SSP (Aihara+ 2022PASJ...74..247A) within the SHELA field. Finally, we include J and (shallower) Ks images from the VICS82 survey (Geach+ 2017, J/ApJS/231/7) obtained with VISTA and CFHT.
