Example of the six density maps for a random simulated neutron star population, which we fed into the SBI pipeline. The top and the bottom row show the P-Ṗ diagrams and the P-Ṗ averaged flux maps for each of the three surveys, respectively. In the top row, the colour represents the density in neutron star number within each bin, while in the bottom row the colour represents the averaged flux in Jy within each bin. For bins without any stars in the bottom row, the average flux has been set to −7.
