Results for the leading stripe mapping. The x axis shows the time difference Δt = t_ps − t_obs between the time when a source region is observed by the spectrograph and when it releases its solar wind package. The y axis shows the probability per bin. The red curves show only source regions with a measured solar wind speed below 350 km s^-1, the green curves represent intermediate speeds from 350 km s^-1 to 600 km s^-1 and the blue curves with speeds above 600 km s^-1. Each panel shows the result for a different leading angle. The dashed vertical lines mark the area where a source regions would be observed at the moment of the solar wind’s release. The colored numbers show Γ_oc in percent with the corresponding errors. The errors are the statistical errors originating from the variation between individual CRs.
