Receiving vectors of muon telescope of cosmic ray station Novosibirsk

open access: yesSolar-Terrestrial Physics, 2016
The method of receiving vectors allows us to determine cosmic ray anisotropy at every moment of time. Also, the method makes it possible to study fast anisotropy fluctuations related to the interplanetary medium dynamics.
