We checked out of the UnDisLo in the morning and drove up to UCSC to spend the day with Conroy, Johnson, Weisz, and Prochaska. At lunch I put on my cray-cray and talked about my theory that any solar-power device will have non-trivial absorption and reflection spectra, because to be efficient it has to stay cold while absorbing lots of energy. If I am right (and I probably am not), this might lead to reliable spectral signatures of life. After that we spent quality time planning paper zero on the spectroscopic calibration paper, tentatively titled "Combining information from photometric and spectroscopic data: Don’t waste your time in spectrophotometric calibration!". We opened a github repo and started writing.
