ASCA Proposals: Accepted Targets for the ASCA Satellite, 1993-2000

NASA HEASARC provides a listing of accepted astronomical targets from proposals submitted for the ASCA (Advanced Satellite for Cosmology and Astrophysics) Guest Observer program. The database includes all accepted targets from Announcements of Opportunities 1 through 8.5, last updated in August 2000. It contains targets selected for the Performance Verification phase and Priority 3 targets, some of which were never observed.

Use Cases

• Analyzing historical target selection for the ASCA satellite based on the proposal acceptance data.
• Studying the distribution of astronomical targets across different proposal cycles (AOs 1-8.5).
• Cross-referencing accepted targets with actual observation logs to study mission planning efficiency.

Strengths

• Includes all accepted targets from a defined range of proposal cycles (AOs 1 through 8.5).
• Provides a direct link to more detailed master and observation log tables for verification.
• Maintained by the authoritative NASA HEASARC service.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data reflects the state of the project as of August 2000; it is a historical archive.
