Atmospheric extinction coefficients [ku, kg, kr] in the [u′, g′, r′ ] bandpasses, for most photometric nights between MJD 51840 and 51970, plotted against one another. The diagonal lines show the relationship (ku ∝ kg ∝ kr) expected if atmospheric extinction is due to a single atmospheric component.
