GALAH data!

Today I got an unexpected treat when Melissa Ness showed me some new GALAH data from the HERMES instrument. The project is intending to take R 28000 spectra of about a million stars, and determine up to 30 element abundances, or something insane like that. Ness and I are looking at whether The Cannon could be used for basic parameter estimation and to assist in the long-run goals of the project. The data look absolutely beautiful and the first attempts with the data make it look like The Cannon will Just Work (tm). We are a bit concerned about continuum normalization, but aren't we always?
