Detailed Description

A class to implement a multilayer approximation to the analytic SLCSAT nighttime atmospheric model. Sasiela p. 61 states the analytic model as

	5e-15	h<18.5
	2.875e-12/h^{2}	18.5 <= h < 110
Cn^{2}(h) =	2.5e-16	110 <= h < 850
	8.87e-7/h^{3}	850 <= h < 7000
	2.0e-16/h^{.5}	7000 <= h < 20500

where the height h is in meters. (Note - there is an inconsistency in Sasiela's statement of the model. Check original source).

To generate a multilayer approximation to this model, the user must supply a vector of layer heights to the constructor. The convention for assigning turbulence weights to the layers is as follows. The C_{n}^{2} profile is integrated from the ground to the midpoint between the first and second layer, and this weight is assigned to the first layer. The profile is integrated from this point to the midpoint between the second and third layers, and this weight is assigned to the second layer. For the highest layer, the profile is integrated from the midpoint between the second highest layer and the highest layer to infinity.
