<a id="epochsigma"></a> epochSigma? | { angleSigma: number | [number, number, number]; moonLongitudeSigma: number | [number, number, number]; sigmaSeconds: number; } | The epoch's clock-error uncertainty as data, present only where it is visible at the app's display scale (sigma(deltaT) >= 10 s, the same threshold the delta_t_uncertain warning uses, so modern charts carry no block and keep their digests). The values are sigmas, ungraded; the app's damping display consumes them and applies its own grades. Rotation-anchored quantities (angles, houses, rise and set) move at the sky's rate, the Moon's longitude at its own; TT planet-to-planet geometry carries no sigma. Additive under the format-version rules; digests incorporate the block as any field. |
epochSigma.angleSigma | number | [number, number, number] | Sigma of rotation-anchored quantities, in grid units. |
epochSigma.moonLongitudeSigma | number | [number, number, number] | Sigma of the Moon's longitude for a UT-tagged instant, in grid units. |
epochSigma.sigmaSeconds | number | sigma(deltaT) in whole seconds (Morrison & Stephenson 2004 table). |
