Path: Link/Optical
% Create an optical link budget.
Assumes divergence limited transmitter.
Has a built-in demo for Pluto mission.

Inputs
------
d (:) Input data structure
d.wavelength Wavelength (m)
d.transmitApertureDiameter Transmit aperture (m^2)
d.thetaOffset Pointing error (rad)
d.transmitPower Transmission Power (W)
d.waveFrontError Wavefront error
Loss is exp(-2*pi*error/wavelength)
d.range Range (m)
