Fig. 3.
Detected pulsars (red dots) and non-detected pulsars (black circles) versus DM and estimated scattering time at 60 MHz divided by the pulsar period. Scattering times at 1 GHz were taken from the Yao et al. (2017) electron density model and scaled to 60 MHz with an exponent, α = −4.0 in τsc ∼ να. Dark blue stars mark pulsars discarded due to an excess of RFI.
