Position, distance, and velocity as a function of of the Sgr stream (Strip sample). (a) Sky distribution with overlaid count contours. The dashed lines represents a regular grid in the Galactic coordinate frame. (b) Smoothed median (orange line) and associated uncertainty (orange area) of the Galactocentric distance for the data (black dots) and LM10 (green line). (c–d) Same as (b) but for the velocity in the (orange) and (blue) directions after correcting for the solar reflex. (e) Median metallicity of the RR Lyrae types AB (orange) and C (blue). (f) Histograms of for the Strip sample – but only after selecting by distance – (orange), for the final Strip sample (blue) and for the nGC3 sample (red). The dashed black line represents the threshold below which we do not compute the median used in the other panels. We also show the positions of the apocentres as two vertical grey stripes (see text).
