- TypeIcBLSNe.RATE_CI: ClassVar[tuple[float, float] | None] = (-0.05928294129707945, 1.8451441371270403)#
Multiplicative (lower, upper) 90% confidence factors on rate.
If a publication reports a rate \(R_0 {}^{+\Delta R_+}_{-\Delta R_-}\), this is
((R_0 - dR_minus) / R_0, (R_0 + dR_plus) / R_0)– see Yield Statistics. Expressed as multiplicative factors (rather than absolute Quantity bounds) so that it applies unchanged to a rate that is itself cosmology-dependent (e.g. a core-collapse SNe subtype, whose rate scales with the instance’s cosmology). None (the default) means no rate uncertainty has been sourced for this class yet; rate_ci then degenerates to the point value rate twice over.
