EUVE Right Angle Program: First Catalog of 114 Extreme-Ultraviolet Sources

114 extreme-ultraviolet sources, including 99 new serendipitous discoveries, were detected by the EUVE satellite's Right Angle Program. Observations covering 8% of the sky were made from January 1993 to January 1994, with exposure times typically two orders of magnitude longer than the all-sky survey. NASA HEASARC created this table in February 2013 based on the original catalog from the reference paper.

Use Cases

• Identify new extreme-ultraviolet sources based on serendipitous detections mentioned in the description.
• Study the nature of EUV-emitting objects like B stars and active galactic nuclei (AGN) listed in the catalog.
• Analyze source detections across the six specific EUVE filter bandpasses referenced in the description.
• Cross-reference alternative source identifications for the listed EUV sources.

Strengths

• Contains 114 distinct EUV sources, with 99 being new serendipitous discoveries.
• Based on 162 discrete pointings with exposure times typically 100 times longer than the EUVE all-sky survey.
• Catalog includes notable detections such as one B star and three extragalactic objects (AGN).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The table contains 152 entries for 114 sources due to separate listings for alternative identifications, which may complicate analysis.
• The description notes the table required extensive hand-editing and corrections, advising users to cross-check contents with the printed source.
