LUPUS3XMM - Lupus 3 SFR XMM-Newton X-Ray Point Source Catalog

Overview

This table contains the analysis results of an XMM-Newton observation of the Lupus 3 region that contains a high proportion of young low-mass (< 0.3 solar masses) T Tauri stars in the Lupus star-forming complex. The observation had a ~22-ks effective exposure in the pn and MOS cameras. The detection of X-ray sources in 0.5 - 4.5 keV images of the Lupus 3 core was performed using the standard source detection method in the XMM-Newton Science Analysis Software (SAS). 102 candidate X-ray sources were detected with a likelihood threshold of >= 12 (corresponding to 4.4 sigma in Gaussian statistics) in the 30-arcmin diameter field-of-view of the EPIC cameras, of which 25 have visible or near-IR counterparts within the adopted 4" correlation radius for each X-ray source that were known to be pre-main sequence stars. Their X-ray luminosities range from 3 x 10²⁸ to 3 x 10³⁰ erg/s. This table gives the list of X-ray sources detected in the core of the Lupus 3 region with the EPIC camera on-board XMM-Newton, except that the X-ray source associated with the star HR 6000 (the nominal target of the XMM-Newton observation of the original PI) has been excluded. Additional information on the optical and IR counterparts of 25 of the X-ray sources, and on the X-ray spectra, is available in the reference paper.

Provenance

This table was created by the HEASARC in Match 2007 based on CDS table J/A+A/454/595 file table6.dat.

Parameters

Source_Number
A running X-ray source number in order of increasing J2000.0 Right Ascension.

Name
The name for th x-ray source using the '[G2006]' prefix (for Gondoin 2006) and the source number value, as recommended by the CDS Dictionary of Nomenclature of Celestial Objects.

RA

Dec
The Declination of the X-ray source in the selected equinox. This was given in J2000.0 coordinates to a precision of 0.1 arcseconds in the original table.

LII
The Galactic Longitude of the X-ray source.

BII
The Galactic Latitude of the X-ray source.

Error_Radius
The positional uncertainty of the X-ray source, in arcseconds.

PN_Count_Rate
The count rate of the X-ray source in the EPIC pn camera, in the 0.5 - 4.5 keV band, in ct/s.

PN_Count_Rate_Error
The uncertainty in the pn count rate in the 0.5 - 4.5 keV band, in ct/s.

M1_Count_Rate
The count rate of the X-ray source in the EPIC MOS1 camera, in the 0.5 - 4.5 keV band, in ct/s.

M1_Count_Rate_Error
The uncertainty in the MOS1 count rate in the 0.5 - 4.5 keV band, in ct/s.

M2_Count_Rate
The count rate of the X-ray source in the EPIC MOS2 camera, in the 0.5 - 4.5 keV band, in ct/s.

M2_Count_Rate_Error
The uncertainty in the MOS2 count rate in the 0.5 - 4.5 keV band, in ct/s.
