Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    Abstract:
        We present the first full catalog and science results for the Nuclear
        Spectroscopic Telescope Array (NuSTAR) serendipitous survey. The
        catalog incorporates data taken during the first 40 months of NuSTAR
        operation, which provide ~20Ms of effective exposure time over 331
        fields, with an areal coverage of 13deg2, and 497 sources detected
        in total over the 3-24keV energy range. There are 276 sources with
        spectroscopic redshifts and classifications, largely resulting from
        our extensive campaign of ground-based spectroscopic follow-up. We
        characterize the overall sample in terms of the X-ray, optical, and
        infrared source properties. The sample is primarily composed of active
        galactic nuclei (AGNs), detected over a large range in redshift from
        z=0.002 to 3.4 (median of <z>=0.56), but also includes 16
        spectroscopically confirmed Galactic sources. There is a large range
        in X-ray flux, from log(f3-24keV/erg/s/cm2)~-14 to -11, and in
        rest-frame 10-40keV luminosity, from log(L10-40keV/erg/s)~39 to 46,
        with a median of 44.1. Approximately 79% of the NuSTAR sources have
        lower-energy (<10keV) X-ray counterparts from XMM-Newton, Chandra, and
        Swift XRT. The mid-infrared (MIR) analysis, using WISE all-sky survey
        data, shows that MIR AGN color selections miss a large fraction of the
        NuSTAR-selected AGN population, from ~15% at the highest luminosities
        (LX>1044erg/s) to ~80% at the lowest luminosities
        (LX<1043erg/s). Our optical spectroscopic analysis finds that the
        observed fraction of optically obscured AGNs (i.e., the type 2
        fraction) is FType2=53-15+14% , for a well-defined subset of the
        8-24keV selected sample. This is higher, albeit at a low significance
        level, than the type 2 fraction measured for redshift- and
        luminosity-matched AGNs selected by <10keV X-ray missions.

    Description:
        Over the period from 2012 July to 2015 November, which is the focus of
        the current study, there are 510 individual NuSTAR exposures that have
        been incorporated into the serendipitous survey. These exposures were
        performed over 331 unique fields (i.e., 331 individual sky regions,
        each with contiguous coverage composed of one or more NuSTAR
        exposures), yielding a total sky area coverage of 13deg2. Table 1
        lists the fields chronologically. The fields have a cumulative
        exposure time of 20.4Ms.

        We have undertaken a campaign of dedicated spectroscopic follow-up in
        the optical-IR bands, obtaining spectroscopic identifications for a
        large fraction (56%) of the total sample.
        Since NuSTAR performs science pointings across the whole sky, a
        successful ground-based follow-up campaign requires the use of
        observatories at a range of geographic latitudes, and preferably
        across a range of dates throughout the sidereal year. This has been
        achieved through observing programs with, primarily, the following
        telescopes over a multiyear period (2012 Oct 10 to 2016 Jul 10): the
        Hale Telescope at Palomar Observatory (5.1m; PIs F. A. Harrison and D.
        Stern); Keck I and II at the W. M. Keck Observatory (10m; PIs F. A.
        Harrison and D. Stern); the New Technology Telescope (NTT) at La Silla
        Observatory (3.6m; PI G. B. Lansbury); the Magellan I (Baade) and
        Magellan II (Clay) Telescopes at Las Campanas Observatory (6.5m; PIs
        E. Treister and F. E. Bauer); and the Gemini-South observatory (8.1m;
        PI E. Treister).

    Note (1): A binary flag indicating whether the source is detected with a false
              probability lower than our threshold of log(PFalse)=-6.
    Note (2): Same as previous columns but after deblending has been performed to
              account for contamination of the source counts from very nearby
              sources (see Section 2.4 of this paper, and Section 2.3.2 of
              Mullaney+ (2015, J/ApJ/808/184). Deblending only affects a
              very small fraction of the overall sample (e.g., see Section 2.4).
    Note (3): A binary flag indicating whether the NuSTAR detected source remains
              significant after deblending, in at least one of the three standard
              energy bands.
    Note (4): Calculated at the source coordinates, and using a source aperture of
              30" radius (see Section 2.4). The values are non-aperture-corrected;
              i.e., they correspond to the 30" values, and have not been corrected
              to the full PSF values.
    Note (5): For the net source counts, we give 90% CL upper limits for sources
              not detected in a given band. Throughout the table, upper limits are
              flagged with a -99 value in the error column.
    Note (6): The average net, vignetting-corrected exposure time at the source
              coordinates. These correspond to the A+B data, so should be divided
              by two to obtain the average exposure per FPM.
    Note (7): Non-aperture-corrected. Determined from the photometric values
              and the exposure times.
    Note (8): Upper limits, lower limits, and sources with no constraints are
              flagged with -99, -88, and -77 values, respectively, in the
              error columns.
    Note (9): After deblending has been performed. These are aperture corrected
              values (i.e., they correspond to the full NuSTAR PSF), and are
              calculated from the count rates using the conversion factors
              listed in Section 2.4.
    Note (10): An abbreviated code indicating the origin of the adopted soft (i.e.,
               low energy; <10keV) X-ray counterpart. Code as follows:
       CXO_CSC = counterparts from the Chandra Source Catalog (CSC; 82 occurrences;
                 Evans+ 2010, Cat. IX/45).
      XMM_3XMM = counterparts from the third XMM-Newton serendipitous source catalog
                 (3XMM; 203 occurrences; Watson+ 2009, J/A+A/493/339 ;
                 Rosen+ 2016, IX/50).
       CXO_MAN = sources manually identified using archival Chandra (27 occurrences)
       XMM_MAN = sources manually identified using archival XMM-Newton
                  (24 occurrences)
       XRT_MAN = sources manually identified using archival Swift XRT data
                  (60 occurrences).
               Section 3.1 details the counterpart matching.
    Note (11): For sources with counterparts in the CSC and 3XMM catalogs. For CSC
               sources we convert to the 3-8keV flux from the 2-7keV flux using a
               conversion factor of 0.83, and for the 3XMM sources we convert from
               the 4.5-12keV flux using a conversion factor of 0.92.
    Note (12): Blanks in the errors indicates the magnitude is a WISE upper limit.

    Note (13): An abbreviated code indicating the origin of the adopted optical
               counterpart to the NuSTAR source. Code as follows:
     SDSS      = sources with soft X-ray counterparts and successful matches in
                 the SDSS DR7 catalog (York+ 2000AJ....120.1579Y); 127 occurrences
     USNO      = sources with soft X-ray counterparts and successful matches in
                 the USNOB1 catalog (Monet+ 2003, I/284); 166 occurrences
     MAN       = sources with a soft X-ray counterpart and a corresponding optical
                 counterpart manually identified in the available optical coverage;
                 181 occurrences
     SDSS_WISE = there is no soft X-ray counterpart to the NuSTAR position, but a
                 WISE AGN candidate is identified within the NuSTAR error circle
                 and successfully matched to the SDSS DR7 (these are mainly used as
                 candidates for spectroscopic followup); 11 occurrences.
     USNO_WISE = there is no soft X-ray counterpart to the NuSTAR position, but a
                 WISE AGN candidate is identified within the NuSTAR error circle
                 and successfully matched to the USNOB1 catalog (these are mainly
                 used as candidates for spectroscopic followup; 6 occurrences).
                 We give a detailed description of the procedure used to identify
                 optical counterparts in Section 3.2.
    Note (14): For the SDSS DR7 matches, this is calculated as R=r-0.16. For
               the USNOB1 matches, this is taken as the mean of the two independent
               photographic plate measurements, R1mag and R2mag. For the manual
               identifications, the magnitude is taken from another optical catalog
               or manually determined from the imaging data.
    Note (15): The large majority of the redshifts were obtained through our own
               campaign of ground-based spectroscopic followup of NuSTAR
               serendipitous survey sources (see Section 3.3.1 and
               the "Description" section above).
    Note (16): Estimated from the observed-frame fluxes, following the procedure
               outlined in Section 2.4. Negative values indicate upper limits. The
               luminosities are observed values, uncorrected for any absorption
               along the line of sight. The intrinsic luminosities may therefore
               be higher, for highly absorbed AGNs.
    Note (17): A binary flag indicating the few sources which show evidence for
               being associated with the primary science targets of their
               respective NuSTAR observations, according to the definition in
               Section 2.3 [{Delta}(cz)<0.05cz].
    Note (18): A binary flag highlighting the sources used in the
               Aird+ (2015ApJ...815...66A) study.

         377  A1    ---     Fl      Primary catalog code (8)

    Note (1): Calculated at the source coordinates. The values are
              non-aperture-corrected.
    Note (2): For the net source counts, we give 90% CL upper limits for sources
              not detected in a given band. Throughout the table, upper limits are
              flagged with a -99 value in the error column. The photometric columns
              are blank where the A+B data prohibit reliable photometric
              constraints.
    Note (3): The average net, vignetting-corrected exposure time at the source
              coordinates. These correspond to the A+B data, so should be divided
              by two to obtain the average exposure per FPM.
    Note (4): Determined from the photometric values and the exposure times.

    Note (5): After deblending has been performed. These are aperture corrected
              values (i.e., they correspond to the full NuSTAR PSF), and are
              calculated from the count rates using the conversion factors
              listed in Section 2.4.
    Note (6): The large majority of the redshifts were obtained through our own
              campaign of ground-based spectroscopic followup of NuSTAR
              serendipitous survey sources (see Section 3.3.1 and
              the "Description" section above).
    Note (7): Estimated from the observed-frame fluxes, following the procedure
              outlined in Section 2.4. Negative values indicate upper limits. The
              luminosities are observed values, uncorrected for any absorption
              along the line of sight. The intrinsic luminosities may therefore
              be higher, for highly absorbed AGNs.
    Note (8): A character indicating the reason for not being included in the
              primary catalog. These are categorised into four groups as follows:
       E = the source is within or very close to the peripheral region of the NuSTAR
           mosaic, which is excluded from the primary source detection (33% of
           cases);
       T = the source is narrowly offset from the central science target position
           for the NuSTAR observation (and thus automatically excluded;
           see Section 2.3), or from another bright source in the field (11%);
       X = the source lies in a region which is masked out, or in a NuSTAR field
           which is excluded, from the primary source detection (44%; e.g., due to
           highly contaminating stray light or a bright science target); or
       L = the source has a comparatively low detection significance (12%).
