Our data compared to the predictions by the model from Peñarrubia et al. (2010). Top panel: equatorial map with the position of our fields plotted over the simulation. Bottom panel: distance vs. RA diagram with our results compared to the model predictions. Fields on the faint branch are denoted with circles, and fields on the bright branch are denoted with squares. Measurements matching the leading arm are denoted in pink, whereas those matching the trailing arm are denoted in light blue. White markers represent detections that can not be unambiguously tagged as leading or trailing; grey markers in the upper panel correspond to fields with more than one MS detection (they unfold in the bottom panel). The colour scales represent the time since the particles from the simulations became unbound.
