Layout of the simulation fields, over-plotted on the Roman GBTDS footprint as recommended by the Roman Observations Time Allocation Committee. The colours represent the total number of simulated microlensing events per simulation field over the average for all fields in the run with the PopSyCLE (Lam et al. 2020) default 350 km/s mean NS kick velocity (before applying the detectability cuts).
