A varying quasar spectrum

I’ve been working on reducing, plotting, and normalizing Gemini spectra over the last little while. Here’s a final product.

Here's an example of the type of spectra I'm working on. In chronological time, the spectra are ordered black, red, blue. This indicates the absorption feature associated with CIV is getting deeper.
