Observed scattering timescales vs frequency. The green circles represent this work, the other markers as per the legend (see inset). The values are queried from the TNS database and the First CHIME/FRB Catalog. The grey lines are a reference for the τ_sc ∝ ν⁻⁴ relation. The darkest grey line corresponds to the CHIME/FRB scattering sensitivity limit of 10 ms at 600 MHz. Apertif, Parkes, ASKAP, UTMOST and MeerTRAP τ_sc are shown at their respective central observing frequencies, while the CHIME/FRB τ_sc are shown at the peak frequency of the burst.
