Update 4/20

Charge Exchange

With a theoretical optical depth as a function of frequency of

\tau = \sigma_{\nu_0} n_{HIhot} d \frac{c}{\nu_0} \sqrt{\frac{m_H}{2 \pi k_B T}} e{-\frac{(\nu - \nu_0)2 c2 m_H}{2 \nu_02 k_B T}}

0.125704 e{-8.92598\times10{-25} (\nu - 2.47\times1015)2)

Which gives an optical depth at \nu_0 of .126, an optical depth at \pm 100 km/s of 0.061.

I've attached a Mathematica notebook with my work.

I've also made it possible to output both the unsplit and split (as separate files) Lyman-alpha absorption from postprocessing. Should be able to get some preliminary results in a day or two.

Spring Code

Split into 10 modules now, approximately 6ish left to refactor. May be able to finish by the end of the week. Almost certainly by the end of the month.
