White light curves and systematics models for all survey targets, with each night of observation displayed separately. Black points correspond to the sigma-clipped flux in the optimal aperture. Red lines represent the systematics model, which comprises a linear trend in time, a linear combination of comparison star light curves, and a combination of additional covariates (airmass, the distance from the median centroid, the PSF width, the time-varying telluric water absorption proxy, no covariates) that minimize the BIC (see Section 2.3 for more information).
