Proper motion as functions of age. Points correspond to the median of the age distribution of stars in each CMD region (Table A.2), while ages of variable stars have been assigned as follows: 0.1 Gyr to Cepheids (CEP), 1 Gyr to long-period variables (LPVs), and 10 Gyr to RR Lyrae stars (RRL). Dashed lines represent the uncertainty on the average proper motion from all LMC stars within the tile. Continuous lines indicate the best weighted least squares fit line.
