Notes. Columns are the same as in Table 1, except for the final two columns, which give the reference to earlier published scintillation results for some sources and a note on the likely cause for our nondetections. For pulsars that have published scintillation results at other frequencies, the relevant reference is given. (a)”low S/N” implies that scintles were detected, but with insufficient S/N to allow robust measurements of the scintillation statistics; in all other cases, likely a combination of lacking sensitivity and frequency resolution would have contributed to the absence of scintles in our data. “insufficient Δf “ means that the used frequency resolution is insufficient to resolve the scintillation to get meaningful measurements.
