% Compute max. navigation error that maintains the specified performance.
Find the maximum possible navigation error in relative velocity so that
the specified deadband will NOT be reached in the specified time, with
a specified probability.

Form:
[sigma_ydot, sigma_d] = RelativeVelocityError( alt, D, t, p, sigma_x, rho_xydot, body );
--------------------------------------------------------------------------
------
Inputs
------
alt (1) Altitude of the orbit [km]
D (1) Deadband in the along-track axis
t (1) Time horizon [orbits]
p (1) Probability that the deadband will NOT be reached
sigma_x (1,m) Standard deviation of relative navigation
radial position error
rho_xydot (1,n) Correlation coefficient
body (:) String name of moon or planet ('earth' is default)
-------
Outputs
-------
sigma_ydot (m,n) Maximum standard deviation of the relative navigation
along-track velocity error
sigma_d (1) Maximum standard deviation of the along-track drift rate
