Notes. The values of this work come from Table 1. v_d and τ_d of the previous studies and the NE2001 simulations are rescaled to our observing frequencies using a scaling index of 4.4 and 1.2, respectively. Besides, as the NE2001 Electron Density Model assumes that all pulsars have a pulsar transverse velocity of 100 km s⁻¹, we also used the estimated pulsar transverse velocities, that are calculated by using Eq. (7) and are listed in Table 3, to adjust the scintillation timescale τd for each pulsar, like Eq. (46) of Cordes & Lazio (1991). The subscripts and superscripts for the previously published scintillation parameters were obtained by adding and subtracting the uncertainties first from the literature and then rescaling. For the NE2001 predictions, the subscripts and superscripts are the predicted values at the lowest and highest frequencies of our bandwidth, respectively. See Sect. 5 for a discussion of the reasons for discrepancies between this work, previous publications and NE2001.
