Recovered signals from a scintillation timescale’s worth of total intensity data processed with cyclic deconvolution. (Top left) Dedispersed pulse profile of PSR B1937+21 before (orange) and after (blue) deconvolution, each with 1024 phase bins. Note that, at higher observing frequencies, a narrow, trailing feature is present in both the main and interpulse components of this pulsar’s profile, and its visibility at 428 MHz is significantly diminished due to profile evolution rather than insufficient pulse-phase resolution (see M. A. Walker et al. 2013). (Top right) Recovered transfer function intensity. (Bottom left) Autocorrelation function and fit for ∣H(ν)∣². (Bottom right) Recovered pulse broadening function intensity (blue) with a time resolution of ≈0.28 μs, the same function smoothed (orange), and a one-sided exponential with an equivalent scattering delay at a 1/e broadening time (dashed purple). Note the shorter tail on the exponential pulse broadening function compared to what was recovered for this observation, indicating disagreement with a thin-screen interpretation.
