Detailed Description

A LogWavelengthDistribution object represents a wavelength probability distribution for which the logarithm of the wavelength is distributed uniformly over a wavelength range configured by the user. Specifically, with \(a\) and \(b\) denoting the minimum and maximum wavelengths, the normalized probability distribution can be written as

\[ p(\lambda) = \begin{cases} \frac{1}{\ln b - \ln a}\,\frac{1}{\lambda} & a < \lambda < b \\ 0 & \mathrm{elsewhere} \end{cases} \]

Using the inversion method, this easily leads to the formula for sampling a wavelength from this distribution:

\[ \ln\lambda = \ln a + (\ln b - \ln a) \mathcal{X} \]

where \(\mathcal{X} \) is a random deviate.
