Difference light curves of the Einstein Cross from the Liverpool-Maidanak brightness records in the gVrRI bands. To construct these difference curves, the multi-band brightness records of B have been subtracted from those of A (top left panel), C (top right panel), and D (bottom panel). In addition to subtracting the records of the least variable image, the resulting difference curves are shifted in magnitude to show variations around the zero level.
