eROSITA Master Catalog: X-ray Observations from Calibration Phase

Over one hundred individual pointing and field scans were performed by the eROSITA X-ray telescope between mid-September and mid-December 2019. This catalog lists observations from the Calibration and Performance Verification program, categorized into Survey fields, Magellanic Clouds, Galactic fields, and Extragalactic fields. NASA HEASARC produced this database table in July 2023 based on information from the German eROSITA Consortium.

Use Cases

• Identify X-ray observation targets based on categorized fields (Survey, Magellanic Clouds, Galactic, Extragalactic).
• Study the spatial distribution of observations relative to the Galactic plane (|Galactic latitude| < 17 deg or > 17 deg).
• Analyze the observation strategy and coverage of the eROSITA Cal-PV program.
• Link observation records to associated eROSITA catalogs and data products for further analysis.

Strengths

• Contains over one hundred individual pointing and field scan observations.
• Observations are categorized into four distinct types (Survey, Magellanic Clouds, Galactic, Extragalactic).
• Includes links to associated eROSITA catalogs and data products where available.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is specific to the Calibration and Performance Verification program from late 2019.
