Comparison of FRB 121102's CHIME/FRB burst drift rate with rates measured by Hessels et al. (2019) at higher observing frequencies. Where multiple bursts are detected with the same instrument (at 1.4 and 2.0 GHz), the weighted average and standard deviation are taken at the central frequencies of the receiver bandwidth and error bars reflect the scatter in the measurements, while the error bars at 600 MHz and 6.5 GHz reflect the measurement errors. Over this frequency range, the drift rate evolves roughly linearly with ∼−150 MHz ms⁻¹ GHz⁻¹.
