Struct
space::irbem::FootPoint
cheatah-space v0.1.0-alpha — Biome Standard 0.6.5-alpha
Where the line crosses a chosen geodetic altitude — IRBEM's FIND_FOOT_POINT.
Constants & variables
The foot, GEODETIC: altitude km, latitude deg, east longitude deg.
IRBEM returns XFOOT in GDZ too, which is the one place in its API where an output frame differs from its input's.
The field vector there, GEO, nT — IRBEM's BFOOT.
Its magnitude, nT — IRBEM's BFOOTMAG.
Stored rather than recomputed because every caller wants it and fixarray::norm is a square root.
