Comment on “Locating the source field lines of Jovian decametric radio emissions” by YuMing Wang et al.

In this comment of the article [arXiv:2002.01150] "Locating source field lines Jovian decametric radio emissions" by YuMing Wang et al., 2020, we discuss assumptions used authors to compute beaming angle Jupiter s emissions induced moon Io. Their method, relying on multi-point observations, was applied a single event observed 14th March 2014 Wind and both STEREO A/B spacecraft from 5 16 MHz, erroneously identified as northern emission (Io-B type) instead southern one (Io-D type). We encourage update their results with right hemisphere origin test method larger sample Jupiter-Io emissions.
