This is an interesting study that extends the classical telescope technique for localized nonlinear structures, magnetic knots. Authors provides mathematical background for such an extension and discuss one possible application, plasmoids in the planetary magnetotails. I think the paper is well written as will be interesting to AnGeo readers. There is only one comment that I would like Authors to consider before publication. Any such analysis technique should have a certain threshold for magnetic field fluctuations that prevent the reconstruction of original magnetic field structure. Readers will be interested in some estimates of this fluctuation level (relative to the ambient field) for the plasmoid reconstruction.

Short summary

The present study discusses the modeling and interpretation of magnetospheric structures via electromagnetic knots for the first time. The mathematical foundations of electromagnetic knots are presented, and the formalism is reformulated in terms of the classical wave telescope technique. The method is tested against synthetically generated magnetic field data describing a plasmoid as a two-dimensional magnetic ring structure.
