precise spectroscopy

I spent my research time today writing notes on paper and then LaTeX in a document, making more specific plans for the projects we discussed yesterday with Zhao (Yale) and Bedell (Flatiron). Zhao also showed me issues with EXPRES wavelength calibration (at the small-fraction-of-a-pixel level). I opined that it might have to do with pixel-size issues. If this is true, then it should appear in the flat-field. We discussed how we might see it in the data.
