space::irbem::OpdPositionFold
cheatah-space v0.1.0-alpha — Biome Standard 0.6.5-alpha
The batch's position caveat, accumulated one point at a time — T89PositionFold's method against this model's envelope.
The envelope is r <= 60 R_E and nothing else, so the largest and smallest squared radii decide the whole batch with no per-point sqrt; the finiteness flag is kept apart because a NaN radius compares false against both extremes.

Fold one position in.

none.
IrbemOpd.BatchReportsTheSameEnvelopeTheScalarLaneDoesWhat the batch's positions say about the model's envelope.
Status::DomainError when any point is not finite or is inside the Earth, Status::OutOfValidityRange when any point is beyond 60 R_E, otherwise Status::Ok.
O(1).
none.
IrbemOpd.BatchReportsTheSameEnvelopeTheScalarLaneDoesConstants & variables
The smallest r^2 seen, R_E^2; +inf until the first point.
The largest r^2 seen, R_E^2; zero until the first point.
The smallest GSM x seen, R_E — carried so the envelope check is the same call the scalar lane makes, though this model publishes no x limit.
False once any point has had a non-finite coordinate.
