Compare equivalent widths

[djperrefort]

The equivalent widths of CMFGEN spectra should be compared against spectral observations from CSP DR2. The equivalent width calculation should ideally follow Folatelli et al. 2013. Doing so will allow us to validate our results while also ensuring any equivalent widths we publish for features not in the CSP paper can be interpreted more easily.

• Calculate pw using feature bounds determined from the observed spectra
• Calculate pw leaving the feature bounds unfixed
• Repeat the CSP silicon plots for Tmax
• Plot modeld and observed pw as a function of phase
• Validate we are converting modeled to observed phase correctly when tabulating pew per phase
