Proper motion measurements for tile e1084. Top: histogram in K_s band for stellar sources in both the first and latest K_s band epochs observed for e1084. About 60% of the sources have counterparts in Gaia DR3. This number dropped to ≲40% for K_s > 16.0 mag. Bottom: Naive PM measurements based on the differences of the RA/Dec between the latest and the first epochs. The grid pattern is an artefact of the binning algorithm used for plotting, and is not a real feature. Only stellar sources with K_s < 16.0 have been used and the timespan is ~4.2 yr (1530 days). The mean values are PM_RA cos Dec = −6.40 ± 5.46 mas yr⁻¹ and PM_Dec = −1.53 ± 5.02 mas yr⁻¹.
