double Isis::AtmosModel::Ei ( double x )

staticinherited

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,

$Ei(x) \sim \frac{e^x}{x} (1 + \frac{1!}{x} + \frac{2!}{x^2} + ...)$

See Also: mathworld.wolfram.com/ExponentialIntegral.html

Parameters

x	Value at which the exponential integral will be computed, x > 0.0

Returns: double The exponential integral for the given x.

Exceptions

Isis::IException::Programmer	"Invalid arguments. Definition requires x > 0.0."
Isis::IException::Math	"Power series failed to converge"

double Isis::AtmosModel::En	(	unsigned int	n,
		double	x
	)

staticinherited

This routine evaluates the generalized exponential integral, E_n(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,

$E_n(x) = e^{-x}(\frac{1}{x + n - \frac{1*n}{x + n + 2 - \frac{2(n+1)}{x + n + 4 - ...}}})$
For $0.0 < x <\sim 1.0$ , series representation is used,
$E_n(x) = \frac{(-x)^{n-1}}{(n-1)!}[- \ln x + \psi (n)] - \sum_{m=0, m \neq n-1}^{\infty}\frac{(-x)^m}{(m-n+1)m!}$
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 E_n(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.

See Also: mathworld.wolfram.com/En-Function.html

Parameters

n	Integer value at which the exponential integral will be evaluated (n >= 0)
x	The exponential integral En(x) will be evaluated

Returns: double Value of the exponential integral for the give n and x.

Exceptions

Isis::IException::Programmer "Invalid arguments. Definition requires (x > 0.0 and n >=0 ) or (x >= 0.0 and n > 1)." @throws Isis::IException::Math "Continued fraction failed to converge" @throws Isis::IException::Math "Series representation failed to converge"

void Isis::AtmosModel::GenerateAhTable ( )

inherited

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.
