Overview

This table contains the source catalog from the Nuclear Spectroscopic Telescope Array (NuSTAR) survey of the Extended Chandra Deep Field South (hereafter, ECDFS), that is currently the deepest contiguous component of the NuSTAR extragalactic survey program. The survey covers the full ~30' x 30' area of this field to a maximum depth of ~360 ks (~220 ks when corrected for vignetting at 3 - 24 keV), reaching sensitivity limits of ~1.3 x 10-14 erg/s/cm2 (3 - 8 keV), ~3.4 x 10-14 erg/s/cm2 (8 - 24 keV), and ~3.0 x 10-14 erg/s/cm2 (3 - 24 keV). 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 - 24 keV band. The 8 - 24 to 3 - 8 keV band ratios of the 12 sources that are detected in both bands span the range 0.39 - 1.7, corresponding to a photon index (Gamma) range of about 0.5 - 2.3, with a median photon index of 1.70 +/- 0.52. The redshifts of the 49 sources in the main sample span the range z = 0.21 - 2.7, and their rest-frame 10 - 40 keV luminosities (derived from the observed 8 - 24 keV fluxes) span the range L10-40keV ~ (0.7 - 300) x 1043erg/s, sampling below the "knee" of the X-ray luminosity function out to z ~ 0.8 - 1. Finally, the authors identify one NuSTAR source that has neither a Chandra nor an XMM-Newton counterpart, but that shows evidence of nuclear activity at infrared wavelengths and thus may represent a genuine, new X-ray source detected by NuSTAR in the ECDFS.

The NuSTAR ECDFS survey consists of observations from two separate passes. Observations making up the first pass were taken between 2012 September and December, and those making up the second pass were taken roughly six months later, between 2013 March and April.

For their cosmological calculations, the authors adopt a Hubble constant H0 of 71 km s-1 Mpc -1, OmegaM of 0.27, and OmegaLambda of 0.73.

This table was created by the HEASARC in September 2017 based on the CDS Catalog J/ApJ/808/184 file catalog.dat.

Parameters

Name

RA
The Right Ascension of the NuSTAR source in the selected equinox. This was given in J2000.0 decimal degrees to a precision of 10-6 degrees in the original table. The position is that of the pixel with the lowest false probability (PFalse) value in the 20"-smoothed maps across all bands. The position is taken from the band showing the lowest PFalse (i.e., the band in which the source is most significantly detected). All following photometry and so on is then performed at this one position in all three bands.

Dec

The Declination of the matched Chandra or XMM-Newton counterpart of the NuSTAR source in the selected equinox. This was given in J2000.0 decimal degrees to a precision of 10-6 degrees in the original table.

Offset
The angular separation between the NuSTAR source and the matched Chandra or XMM-Newton source, in arcseconds.

Ctrprt_3_8_keV_Flux
The observed-frame 3 - 8 keV flux derived from the Chandra or XMM-Newton data, in erg s-1 cm-2, of the specified counterpart of the NuSTAR source. Note that these data are not provided in the catalogs of L05 (Lehmer et al. 2005, ApJS, 161, 21), R13 (Ranalli et al. 2013, A&A, 555, A42) or X11 (Xue et al. 2011, ApJS, 195, 10), because the 3 - 8 keV band is not a standard band in those papers. Instead, the 3 - 8 keV fluxes were calculated using ACIS Extract (Broos et al. 2010, ApJ, 714, 1582) with a simple power-law model.

Combnd_3_8_keV_Flux
The total, combined observed-frame 3 - 8 keV flux derived from the Chandra or XMM-Newton data, in erg s-1 cm-2, of all Chandra or XMM-Newton sources within 30 arcseconds of the NuSTAR source. Note that these data are not provided in the catalogs of L05 (Lehmer et al. 2005, ApJS, 161, 21), R13 (Ranalli et al. 2013, A&A, 555, A42) or X11 (Xue et al. 2011, ApJS, 195, 10), because the 3 - 8 keV band is not a standard band in those papers. Instead, the 3 - 8 keV fluxes were calculated using ACIS Extract (Broos et al. 2010, ApJ, 714, 1582) with a simple power-law model.

Spect_Redshift
The spectroscopic redshift of the matched Chandra (from Silverman et al.2010, ApJS, 191, 124) or XMM-Newton (from Ranalli et al. 2013, A&A, 555, A42) source, where available.

Phot_Redshift
The photometric redshift of the matched Chandra (from Silverman et al.2010, ApJS, 191, 124) or XMM-Newton (from Ranalli et al. 2013, A&A, 555, A42) source, where available.

Redshift
The adopted redshift used to calculate the rest-frame 10 - 40 keV luminosity of the NuSTAR source. In cases where both spectroscopic and photometric redshifts are available, the authors always adopt the spectroscopic redshift.

RF_10_40_keV_Lum
The derived rest-frame 10 - 40 keV luminosity of the NuSTAR source for sources where a redshift is available (either photometric or spectroscopic), in erg s-1. Luminosities are calculated using the observed 8 - 24 keV band flux, and k-corrections are performed assuming a photon index of Gamma = 1.8 (see Section 2.3.4 of the reference paper). Where a NuSTAR source is matched to more than one Chandra or XMM-Newton source (and therefore may have more than one associated redshift), the authors provide the 10 - 40 keV luminosity assuming each of the various available redshifts.

RF_10_40_keV_Lum_Error
The uncertainty in the derived rest-frame 10 - 40 keV luminosity of the NuSTAR source for sources where a redshift is available (either photometric or spectroscopic), in erg s-1. Errors are propagated directly from the errors on the 8 - 24 keV fluxes (i.e., the authors assume zero error in the redshift values). Again, negative error values indicate those sources that are detected at less than 3 sigma in a given band.

Source_Flag
A note concerning the source NuSTAR J033202-2746.7 for which this flag parameter is set to 'n'. In Del Moro et al. (2014, ApJ, 786, 16) this source is named NuSTAR J033202-2746.8. The name change is due to minor changes in the authors' data reduction since that publication. The authors note that these changes do not affect any of the science results in Del Moro et al. (2014).
