Instrumental trends for spectroscopic observations of GJ 3470. Left: GMOS. The effects of intermittent cirrus are apparent in the raw stellar flux; this also increases the scatter in the relative light curve. Right: MOSFIRE. Some parameters appear double-valued because data were taken while alternating between two nod positions on the slit. The data shown here are available as an electronic supplement to this article.
