NGC 2362 Chandra X-Ray Point Source Catalog with Optical Identifications

NASA HEASARC provides a catalog of 387 X-ray point sources detected in the young star cluster NGC 2362 using the Chandra ACIS-I instrument. The table lists basic X-ray properties and proposed identifications with optical stars using photometric data from multiple astronomical surveys. This table was created by the HEASARC in March 2007 based on data from the CDS.

Use Cases

• Classifying cluster members versus field objects based on positions in the HR Diagram mentioned in the description.
• Studying X-ray properties of young stellar objects based on the 387 detected point sources.
• Cross-matching X-ray sources with optical counterparts using the described photometric data from Moitinho et al. and Dahm.
• Analyzing the effectiveness of the PWDetect wavelet-based source detection algorithm for X-ray astronomy.

Strengths

• Contains 387 detected X-ray point sources.
• Detection threshold was chosen to ensure no more than one spurious detection in the entire ACIS field of view.
• Includes optical identifications and classifications based on multiple referenced photometric surveys.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
