Distances of LOTAAS discoveries above/below the Galactic plane versus their distance along the Galactic plane, as predicted by the NE2001 (Cordes & Lazio 2002) and YMW16 (Yao et al. 2017) models for the Galactic free electron density distribution. The colour of each point denotes the DM of the pulsar compared to the maximum predicted DM along the particular line-of-sight. The pulsars for which the YMW16 model predicts maximum DMs less than the observed DMs are plotted with black triangles, where the distances to the pulsars are fixed at a limit of 4 kpc above or below the Galactic plane.
