Improving the light curves of gravitationally lensed quasars with Gaia proper motion data

C. Sorgenfrei, R. W. Schmidt, J. Wambsganss

We show how to significantly improve difference image analysis (DIA) of gravitationally lensed quasars over long periods of time using Gaia proper motions. DIA requires the subtrac…
