Description
127 X-ray sources detected in the NGC 1333 star-forming region by the Chandra X-Ray Observatory on 2000 July 12.96 - 13.48. The catalog, produced by the National Aeronautics and Space Administration, contains X-ray, optical, and near-infrared information for 109 significant sources after excluding 8 deemed spurious. It includes 95 sources identified with known cluster members, with X-ray luminosities ranging from log L_X ~ 28.0 to 31.5 erg s^-1.
Use Cases
Analyze the X-ray luminosity function of young stellar objects based on the reported range of log L_X ~ 28.0 - 31.5 erg s^-1.
Study the correlation between X-ray emission and stellar outflows based on the detection of 7 out of 20 known YSOs producing jets.
Investigate interstellar absorption effects on X-ray sources based on the provided column density range of log N_H ~ 20 to 23 cm^-2.
Compare X-ray and near-infrared source properties based on the mention of K-band source counts and counterparts in non-X-ray bands.
Strengths
127 sources detected with most having sub-arcsecond positional accuracy.
95 X-ray sources are identified with known cluster members, providing a high association rate.
73% of the 109 significant sources have counterparts in a non-X-ray band, facilitating multi-wavelength analysis.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Sensitivity decreases by a factor of 4 at the edge of the field compared to the central regions.
