NuSTAR surveys: ECDF-S catalog

The survey covers the full ~30'x30' area of this field to a maximum depth of ~360ks (~220ks when corrected for vignetting at 3-24keV), reaching sensitivity limits of ~1.3x10^-14^erg/s/cm^2^ (3-8keV), ~3.4x10^-14^erg/s/cm^2^ (8-24keV), and ~3.0x10^-14^erg/s/cm^2^ (3-24keV).

A total of 54 sources are detected over the full field, although five of these are found to lie below our significance threshold once contaminating flux from neighboring (i.e., blended) sources is taken into account. Of the remaining 49 that are significant, 19 are detected in the 8-24keV band. The 8-24 to 3-8keV band ratios of the 12 sources that are detected in both bands span the range 0.39-1.7, corresponding to a photon index range of {Gamma}~0.5-2.3, with a median photon index of {Gamma}{bar}=1.70+/-0.52.
