DVReentry:

Path: Orbit/OrbitManeuver

% Computes the delta-V for reentry from a near-circular orbit.
 You must select the entry interface radius, rEI and c! and c2 which are
 the LTVCON (Linear Terminal Velocity Constraint) constants such that

   vR = c1 + c2*vH
   
 where vR is the radial velocity and vH is the horizontal velocity.

   Form:
   dV = DVReentry( a, e, rEI, c1, c2, mu )
