Jeans derived υ_c for the six Aurigaia mocks from Grand et al. (2018). The green dashed line with shaded region shows the result for the simulation particles. The orange line shows the result for the full mock catalogue with only a magnitude limit at G < 20. The red points show the results for the full mock with our data quality cuts. The blue points show the result for the observed mock sample. This is the sample shown in Fig. 13 and described in Table 3. The black line and shaded region show υ_c,true and its associated 1σ variation.
