VizieR Online Data Catalog: Chandra DF obscured & Compton-thick AGNs. I. Variability (Li+, 2019)

This work is based on the Chandra data in the 7Ms CDF-S main-source catalog (Luo+ 2017, J/ApJS/228/2) and the 2Ms CDF-N main-source catalog (Xue+ 2016, J/ApJS/224/15). The source spectra from individual observations were extracted using the ACIS Extract (AE) software package (Broos+ 2010ApJ...714.1582B).

Throughout this paper, we adopt a Galactic column density of N_H=8.8x10¹⁹cm^-2 for the CDF-S and N_H=1.6x10²⁰cm^-2 for the CDF-N (Stark+ 1992, VIII/28). We adopt cosmological parameters of H₀=70.0km/s/Mpc, Ω_M=0.30, and Ω_Λ=0.70.
