Isotropic atmospheric scattering in the first approximation The model for scattering for a general, non-Lambertian surface with an atmosphere looks like this:
P = Pstd + trans*(rho*Ah*munot)/(1.d0-rho*Ab*sbar) trans0*rho*(psurf-Ah*munot)
where P is the overall photometric function (the model of the data), PSTD is the pure atmospheric-scattering term, PSURF is the surface photometric function, AH*MUNOT is a Lambertian approximation to this with hemispheric albedo AH, TRANS and TRANS0 quantify transmission of surface reflected light through the atmosphere overall and with no scatterings in the atmosphere, and finally SBAR quantifies the illumination of the ground by the sky. RHO is the ratio of the sur- face albedo to the albedo assumed in the functional form of PSURF.

This routine computes the exponential integral, Ei(x).
This is defined as
\[ Ei(x) = - \int_{-x}^{\infty} \frac{e^{-t}}{t}\mathrm{d}t = \int_{-\infty}^{x} \frac{e^{t}}{t}\mathrm{d}t \]
for x > 0.
For small x, this method uses the power series,
\[ Ei(x) = \gamma + \ln x + \frac{x}{1*1!} + \frac{x^2}{2*2!} + ... \]
where \( \gamma = 0.5772156649... \) is Euler's constant, and for large x, the asymptotic series is used,
\[ Ei(x) \sim \frac{e^x}{x} (1 + \frac{1!}{x} + \frac{2!}{x^2} + ...) \]

This routine evaluates the generalized exponential integral, En(x).
This is defined as
\[ E_n(x) = \int_{1}^{\infty} \frac{e^{-xt}}{t^n}\mathrm{d}t \mathrm{ for } x \in \mathbb{R }, n \in \mathbb{Z } \mathrm{such that } x \ge 0.0, n \ge 0 \]
Notice that if x = 0, then the equation is not defined for n = 0 or n = 1, as these will result in \( E_n(x) = \infty \).
This method uses the following for cases:
For n > 1 and x = 0.0,
\[ E_n(0) = \frac{1}{n-1} \]
For n = 0 and x > 0.0,
\[ E_0(x) = \frac{e^{-x}}{x} \]
For \( x >\sim 1.0 \), Lentz's continued fraction algorithm is used,
\[ E_n(x) = e^{-x}(\frac{1}{x + n - \frac{1*n}{x + n + 2 - \frac{2(n+1)}{x + n + 4 - ...}}}) \]
\[ E_n(x) = \frac{(-x)^{n-1}}{(n-1)!}[- \ln x + \psi (n)] - \sum_{m=0, m \neq n-1}^{\infty}\frac{(-x)^m}{(m-n+1)m!} \]
where \( \psi (1) = \gamma \) and \( \psi (n) = - \gamma + \sum_{m=1}^{n-1} \frac{1}{m}\) and \( \gamma = 0.5772156649... \) is Euler's constant.The parameter n is of type unsigned int since n cannot be negative.
The routine allows fast evaluation of En(x) to any accuracy, \(\epsilon\), within the reach of your machine's word length for floating-point numbers. The only modification required for increased accuracy is to supply Euler's constant with enough significant digits.

This method computes the values of the atmospheric Ah table and sets the properties of the atmospheric Ah spline.
It obtains the hemispheric albedo by integrating the photometric function times mu over mu = 0 to 1 and then over phi = 0 to 2*pi to calculate the hemispheric reflectance Ah needed for the photometric model with atmosphere. The Trapezoid rule is applied to the table of Ah to obtain bihemispheric albedo Ab. The parameter p_atmosAtmSwitch is set to 0 to integrate Ah.

This method computes the values of the atmospheric Hahg and Hahg0 tables and sets the properties of the atmospheric Hahg and Hahg0 splines.
It integrates functions involving the single particle phase function (assumed to be Hapke Henyey-Greenstein) over mu = 0 to 1 and then over phi = 0 to 2*pi to calculate the corrections needed for the anisotropic photometric model with atmosphere. The Trapezoid rule is applied to the table of Ah to obtain bihemispheric albedo Ab. The parameter p_atmosAtmSwitch is set to 1, 2, 3 to evaluate the 3 required integrals.

This method is a modified version of the GenerateHahgTables method and is used solely for shadow modeling.
Unlike the GenerateHahgTables method, this method does not tabulate the first or third integrals. It only evaluates the middle integral that corrects the sbar variable (illumination of the ground by the sky).
