Δ(CduC-Gaia) coordinate differences for standard and multiple imaging data for the single-exposure plate #886. In multiple imaging, the coordinates are mean values of coordinates derived over several images and astrometric fits. The red and green dots are for standard and multiple imaging, respectively. The lines connect the data points of each star. The data shown in panel a) is for stars that have the Δ(CduC-Gaia) coordinate difference in standard imaging greater than 0.4″ and that have a magnitude G_BP > 13 mag. The circle has a radius of 0.4″. The data shown in panel b) is for stars that have the Δ(CduC-Gaia) coordinate difference in standard imaging greater than 0.3″ and that have a magnitude G_BP < 13 mag. The circle has a radius of 0.3″.
