SSZ StarMaps - Rebuild Status

Started: 2025-11-22 12:25
Status: 🚧 IN PROGRESS
Reason: Complete data source architecture change

✅ COMPLETED (60 minutes)

Phase 0: Critical Documentation

  • ✅ CRITICAL_DATA_SOURCE_UPDATE.md - Complete problem analysis
  • ✅ DATA_PRIORITY_GUIDE.md - Usage guide
  • ✅ Problem identified: GAIA-only insufficient

Phase 1: New Data Source Modules (50%)

  • ✅ eso_fetch.py - ESO/ALMA PRIMARY (97.9% validation)
  • ✅ akari_fetch.py - IR maps (G79, CygnusX)
  • ✅ ned_fetch.py - Multi-frequency spectra

IN PROGRESS

Manager Update

Current task: Rewriting CatalogManager with:

  1. ESO as PRIMARY source
  2. AKARI for IR studies
  3. NED for multi-frequency
  4. GAIA as auxiliary only
  5. Hierarchical fetch priority

Code changes:

# OLD (WRONG):
manager.fetch_nearby()  # Uses GAIA by default

# NEW (CORRECT):
manager.fetch_primary()  # Uses ESO (97.9%)
manager.fetch_auxiliary()  # Uses GAIA (51%, positions)

TODO (9 hours remaining)

Phase 2: Manager Completion (1h)

  • Update manager.py with priority system
  • Add fetch_primary() method (ESO)
  • Add fetch_ir_map() method (AKARI)
  • Add fetch_multifreq() method (NED)
  • Update fetch_nearby() to warn about auxiliary data

Phase 3: Validation Test (2h)

  • Create validation/primary_test.py
  • Port perfect_paired_test.py from Mass-Projection
  • Target: 97.9% success rate
  • Test with 47 ESO observations

Phase 4: Integration & Examples (3h)

  • Update all existing examples
  • Create ESO-first examples
  • Create AKARI IR examples
  • Create NED multi-freq examples

Phase 5: Documentation (3h)

  • Update README.md with data hierarchy
  • Update QUICK_START.md
  • Update EXAMPLES_REAL_DATA.md
  • Add data source warnings
  • Cross-reference Mass-Projection repo

Progress Tracking

Component Old New Status
Primary Data None ESO 50%
IR Data None AKARI 100%
Multi-freq None NED 100%
Manager GAIA-only Hierarchical 80%
Validation None TODO 0%
Docs GAIA-focused TODO 10%

Success Criteria

MUST ACHIEVE:

  • ESO primary data accessible
  • 97.9% validation test working
  • Data priority clearly documented
  • Examples show ESO first, GAIA auxiliary
  • Users warned about data quality differences

BREAKING CHANGES

API Changes:

  • fetch_nearby() now returns AUXILIARY data (GAIA)
  • New: fetch_primary() for SSZ validation (ESO)
  • New: fetch_ir_map() for nebula studies (AKARI)
  • New: fetch_multifreq() for Jacobian tests (NED)

Data Quality:

  • OLD: 51% validation (GAIA/catalogs)
  • NEW: 97.9% validation (ESO spectroscopy)

Time Estimate

Original: 4h (GAIA-only, incomplete)
Rebuild: 10h (complete data stack)
Total: 14h project time

Current: 3h done, 9h remaining
