post-starburst environments, SDSS sky

I nearly finished the response-to-referee for the post-starburst galaxy environments paper. Nearly is a relative word.

Blanton and I had some back-and-forth (and Blanton did a lot of work) on fitting the sky in SDSS imaging for very large, very low-redshift galaxies. Our current page of nearby RC3 galaxies shows many data artifacts, many of which relate to sky-level tracking. The problem is not easy to solve. This is annoying, because the SDSS is drift-scanned, which greatly improves the consistency and simplicity of the sky!
