Detailed Description

Container for sector χ² (or max likelihood) analysis results.

The SECTOR command analyzes how χ² changes as the fit range is extended from the first good bin (fgb) to progressively later times. This helps identify:

• Optimal fitting windows
• Time regions with systematic deviations
• Data quality issues
• Relaxation component contributions

A "sector" is a time window [fgb, fLast] where fLast < lgb. The class stores χ²/maxLH and NDF for each sector, both for the total fit and for individual runs.

Use case: If early-time data shows poor χ², the sector analysis reveals whether to adjust t0, fgb, or background estimation.
