Kvant TTM/COMIS: X-Ray Source Catalog from Mir-Kvant Observatory, 1988-1998

A catalog of 67 X-ray sources detected in the 2-30 keV energy band by the TTM/COMIS telescope onboard the Mir-Kvant observatory. The sources were observed at a confidence level higher than 4 sigma between 1988 and 1998. This table was created by NASA's HEASARC in April 2011 based on a CDS catalog file.

Use Cases

• Identify and catalog X-ray sources based on detection confidence levels mentioned in the description.
• Study the spectral properties of different X-ray source types as referenced in the source paper.
• Analyze long-term X-ray source observations from a specific satellite mission (Mir-Kvant).
• Cross-reference source detections with other astronomical catalogs for multi-wavelength studies.

Strengths

• Contains 67 distinct X-ray sources.
• Sources were detected at a high confidence threshold (> 4 sigma).
• Data covers a significant 10-year observation period (1988-1998).

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.
