SAXWFCCAT2 - BeppoSAX Wide Field Camera Unbiased X-Ray Source Catalog

HEASARC
Archive

Overview

During the operational life of the Italian/Dutch X-ray satellite (1996-2002), BeppoSAX, its two Wide Field Cameras (WFCs) performed observations that covered the full sky at different epochs. Although the majority of the analyses performed on BeppoSAX WFC data concentrated on the detection of transient sources, the authors have now applied the same techniques developed for the INTEGRAL/IBIS survey so as to produce a similar analysis of the BeppoSAX WFC data. This work represents the first unbiased source list compilation produced from the overall WFC data set which is optimized for faint persistent source detection. This approach recovered 182 more sources compared to the previous WFC catalog reported in Verrecchia et al. (2007, A&A, 472, 705; the HEASARC SAXWFCCAT table). The present catalog contains 404 sources detected between 3 and 17 keV, 10 of which are yet to be seen by the new generation of telescopes.

Provenance

This table was created by the HEASARC in July 2011 based on an electronic version of Table 3 from the reference paper which was obtained from the ApJS web site.

Parameters

Name
A commonly used designation for the source. Sources discovered by the WFC have been given J2000.0 position-based names with the 'WFC' prefix, e.g., 'WFC J1452-5708'.

Source_Flag
A non-blank value of this flag parameter indicates a note for the particular source which is coded as follows:

   b = a new detection with respect to Verrecchia et al. (2007, A&A, 472, 705).
   1 = data containing Sco X-1 were too noisy to be added in the total
       mosaic map.
   2 = see Section 4.2.1 of the reference paper.
  

RA
The Right Ascension of the WFC source in the selected equinox. This was given in J2000.0 decimal degrees to a precision of 0.001 degrees in the original table in the reference paper.

Dec
The Declination of the WFC source in the selected equinox. This was given in J2000.0 decimal degrees to a precision of 0.001 degrees in the original table in the reference paper.

LII
The Galactic Longitude of the WFC source.

BII
The Galactic Latitude of the WFC source.

SNR
The number of sigma of the WFC source detection.

Error_Radius
The radius of the error circle (90% confidence) of the source, extrapolated from Figure 5 of the reference paper and with the systematic error included, in arcseconds (converted from the arcminutes used in the original table).

Flux_3_17_keV
The average estimated 3-17 keV flux of the source, in mCrab (see Section 4.1 of the reference paper for more details).

Flux_3_17_keV_Error
The uncertainty in the 3-17 kev flux of the source, in mCrab. This includes both the statistical and the systematic errors (see Section 3.4 of the reference paper for more details.

Flux_17_28_keV
The average estimated 17-28 keV flux of the source, in mCrab (see Section 4.1 of the reference paper for more details).

Flux_17_28_keV_Error
The uncertainty in the 17-28 kev flux of the source, in mCrab. This includes both the statistical and the systematic errors (see Section 3.4 of the reference paper for more details.

Source_Type
The source type classification according to the following schema:

    AGNs: active galactic nuclei;
    BL Lac: BL Lac object;
    cluster: cluster of galaxies;
    CV: cataclysmic variable;
    HMXB: high-mass X-ray binary;
    LMXB: low-mass X-ray binary;
    QSO: quasar;

    Sy2: Seyfert 2 galaxy;
    unid: unidentified source;
    StC: star cluster,
    XRB: galactic X-ray binary;
    XP: X-ray pulsar.
  

Source_Subtype
The source subtype classification according to the following schema:

    A: atoll-type source (neutron star);
    B: burster (neutron star);
    Be: B-type emission-line star;
    BHC: black hole candidate;
    D: dipping;
    DN: dwarf nova;
    G: globular cluster X-ray source;
    IP: intermediate polar;
    M: microquasar,
    P: polar;
    symb: symbiotic star;
    SG: supergiant;
    Z: Z-type source.
  

Class
The HEASARC Browse object classification, based on the source_subtype and source_type parameter values.
