libera_utils.footprint_matching.aggregation.check_coverage(coverage: float, *, accept_threshold: float = 0.75, partial_threshold: float = 0.95) → tuple[bool, bool]#

Apply the CERES 75%/95% coverage rule.

Parameters:

  • coverage (float) – Fraction in [0, 1] of the PSF’s in-contour energy backed by usable data, as the weigher reports it (WeightField.coverage).

  • accept_threshold (float, optional) – Lower bound for acceptance (default 0.75) and for full (non-partial) coverage (default 0.95).

  • partial_threshold (float, optional) – Lower bound for acceptance (default 0.75) and for full (non-partial) coverage (default 0.95).

Returns:

(accept, partial). accept is False below accept_threshold; partial is True in the [accept_threshold, partial_threshold) band.

Return type:

tuple[bool, bool]
