ROSAT XUV Pointed Phase: 1022 Source Detections from 1990-1994

1022 independent source detections from 5916 pointed observations by the ROSAT Wide Field Camera in the extreme UV range (17-210eV). The catalogue corresponds to 328 individual sources, with 113 being new discoveries and 274 having optical counterpart identifications. This data was processed by NASA HEASARC from observations between June 1990 and July 1994.

Use Cases

• Cross-matching XUV sources with optical catalogues based on provided counterpart identifications and spectral classes.
• Analyzing source variability based on repeated observations of the same 328 individual sources.
• Studying the properties of new XUV sources not listed in prior catalogues like '2RE'.
• Filter-specific analysis of XUV observations using the S1, S2, P1, and P2 filter data.

Strengths

• Contains 1022 independent source detections from 5916 pointed observations.
• Includes 113 new sources not listed in the prior '2RE' catalogue.
• Provides optical counterpart identifications with spectral class for 274 sources.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the 1990-1994 observation period.
