TiltAngCovScale
MATLAB
[thetaCovX,thetaCovY,tvar] = TiltAngCovScale(lambda,D,G,...
                                  Atm,[DispCov])
Description

Computes the covariance scale lengths for modeling Kolmogorov angular tilt anisoplanatism as a Markov random process in 2 dimensions. Returns angular scale lengths and tilt variance quantities for modeling tilt angular covariance as: $C_{X}(a,0) = tvar*exp(-a/thetaCovX)$ and $C_{Y}(a,0) = tvar*exp(-a/thetaCovY)$
