VizieR Online Data Catalog: F125W and UV mag of 6.0<z<8.2 galaxies candidates (Jung+, 2022)

We extracted HST slitless grism spectra of 148 high-z galaxies in the GOODS fields from the CANDELS Lyα Emission at Reionization (CLEAR) survey. The CLEAR Experiment is a cycle 23 HST observing program (Program GO-14227, PI: C. Papovich), which observed 12 fields in the CANDELS GOODS fields to 10 to 12 orbit depth with the G102 grism in the HST/WFC3 camera. Each field was observed at three position angles (separated by >10 degrees) to properly correct galaxy spectra from contamination.

The data set has been extended to include all publicly available HST/WFC3 G102 and G141 grism observations in the CLEAR fields. While the primary CLEAR spectral extractions were made for galaxies based on the 3D-HST GOODS catalog, Skelton+ (2014, J/ApJS/214/24), we extracted the CLEAR spectra of high-z galaxies based on the updated HST CANDELS photometry and its segmentation maps from Finkelstein+ (2022ApJ...928...52F). Visual inspection was performed for removing any artifacts and checking the quality of photometry. See Section 2.1.

We also used supplemental data from Keck DEIMOS and MOSFIRE observations. See Section 2.3.

We utilized the HST ACS and WFC3 broadband photometry (B435, V606, i775, I814, z850, Y105, J125, JH140, and H160) in addition to Spitzer Infrared Array Camera (IRAC) 3.6um and 4.5um band fluxes to derive the properties of our 148 sources. UV magnitudes of galaxies were calculated from the averaged fluxes over a 100Å-bandpass (at 1450-1550Å) from the best-fit models, which were not dust-corrected. In our SED fitting, we fixed redshifts with the best-fit photometric redshifts calculated by EAZY. See section 2.4.

In this work, we assume the Planck cosmology with H₀=67.8km/s/Mpc, Ω_M=0.308, and ω_Λ=0.692. All magnitudes are given in the AB system.
