The abstract, sentence by sentence
Recent observations have revealed structure on small angular scales in the anisotropy data of cosmic rays at multi TeV energies. Even though the absolute amplitudes are very small, these effects are somewhat surprising and a wide range of possible causes have been discussed. A possible origin associated with heliospheric electric fields is proposed.

Original abstract
Recent observations have revealed structure on small angular scales in the anisotropy data of cosmic rays at multi TeV energies. Even though the absolute amplitudes are very small, these effects are somewhat surprising and a wide range of possible causes have been discussed. A possible origin associated with heliospheric electric fields is proposed.

However, the most useful data sets for our purposes are those published by the IceCube/IceTop collaboration [ref] for high-energy ($≳100$ TeV) CRs, because these data are free from features caused by heliospheric fields, which demand a different explanation [ref] .

Magnetic reconnections in the heliotail [ref] , non-isotropic particle transport in the heliosheath [ref] or the heliospheric electric field structure [ref] have also been considered as a source of these small-scale anisotropies.

The mechanism proposed here is completely distinct from, and conceptually much simpler than, those suggested by Lazarian and Desiati [ref] although both seek to relate the small-scale structure observed in the anisotropy data to heliospheric structure.

While a number of authors have recently discussed interpretations of the large angular scale anisotropies in terms of cosmic ray source and transport models (e.g. [ref] and references therein) little attention, with the notable exceptions of [ref] , appears to have been paid to the small-scale structure which, as pointed out in [ref] , is quite puzzling and hard to understand.
