Distribution of selected blue stars in galactocentric cylindrical coordinates for the three DP1 fields, as marked in the legend. The starting sample sizes are listed in the last column in Table 1. After further cuts (g − r < 0.6 and 4.0 < M_r < 5.5), the three subsamples include 378 (ECDFS), 387 (EDFS) and 3452 (SV 95 −25) stars. Note: the poor coverage of the R–Z plane with only three pencil beams.
