Δ period0.000s
Δ eccentricity1.4e-5

A radial burn changes eccentricity without changing the period to first order, so it produces no secular along-track drift.

Burn is short relative to the orbital period, so the impulsive approximation used above holds.

No downstream screening on file for this burn. Historical burns retain their record but not the re-screening that followed.
