Bit more research chatting with OSU grad students.
Skype conversation with my grad student Laura Chajet, about fitting absorption troughs.
Worked on two new cases of BAL variability from SDSS-III, including adapting existing software to more easily deal with SDSS-III spectra. Time spent writing code now will pay off in not having to repeat the same processing steps in the future (obvious, yes; but when I'm teaching I find I opt for the what's-quickest-now approach instead of what's-best-in-the-long-run).
Investigated whether a list of BALs bright enough for MDM spectroscopy have pre-existing X-ray observations. Some do, making them good targets for spectroscopic monitoring (and a 2nd epoch of X-ray data if their troughs are seen to vary).
