- property ExposureCatalog.coverage_fraction: dict[str, float]#
Each transient type’s time- and sky-averaged coverage fraction.
\[f_{\rm cov} = \frac{\mathcal E}{4\pi\,{\rm sr}\times T},\]where \(\mathcal E\) is total_effective_exposure and \(T\) is total_duration. This is the fraction of the full \(4\pi\) sky-time volume the survey’s actual footprint swept out –
1.0only for a survey that observes the whole sky continuously over time_bins’ entire span.
