Comparison between MITO and other directional muon telescopes. In Kuwait, a different approach is used, using four layers of proportional counter tubes (PCT) instead of scintillators. The viewing angle and maximum zenith angle have not been taken from the official specifications of each telescope, but they are approximate values obtained by calculation from each telescope dimensions in order to make a rough comparison between MITO and other telescopes. The value of the maximum zenith angle corresponds to the vertical plane of the diagonal. Detection areas and counting rates have been taken from (Munakata et al., 2018).
