Proper motion trends with of the candidate RR Lyrae of the Sgr stream in the Strip sample. (a) Proper motion in Galactic longitude coloured according to proper motion in Galactic latitude. (b) Same as above but substituting longitude with latitude. (c) Total proper motion coloured by distance. In all these panels, we show the predictions from the LM10 model with solid (first wrap) and dashed (second wrap) green lines, as well as the smoothed median from A20 (dashed-dotted black line). Panel d contains the residuals of the smoothed median of the total proper motion (blue – first wrap, orange – second wrap) minus that of A20. Panel e similarly, shows the residuals with respect to the LM10 model.
