Agreement between g-band nightly photometry and Ubercal photometry of ﹩\gt 1﹩ million stars and the dependence on magnitude, MJD, airmass, and focal plane position. Different colors of the points represent bins of stellar colors. In the right panel, arrows indicate that the R14 discrepancy with the catalog photometry near the center of the focal plane was >0.1 mag.
