We analyze the sidereal daily variations observed between 1985 and 2006 atMatsushiro, Japan (MAT) and between 1993 and 2005 at Liapootah, Tasmania (LPT).These stations comprise the two hemisphere network (THN) of underground muondetectors in Japan and Australia. Yearly mean harmonic vectors at MAT and LPTare more or less stable without any significant change in phase and amplitudein correlation with either the solar activity- or magnetic-cycles. In thispaper, therefore, we analyze the average anisotropy over the entire observationperiods, i.e. 1985-2006 for MAT and 1993-2005 for LPT. We apply to the THN dataa best-fitting analysis based on a model anisotropy in space identical to thatadopted by Amenomori et al. (2007) for Tibet III data. The median energies ofprimary cosmic rays recorded are ~0.5 TeV for THN and ~5 TeV for the Tibet IIIexperiment. It is shown that the intensity distribution of the best-fitanisotropy is quite similar to that derived from Tibet III data, regardless ofthe order of magnitude difference in energies of primary particles. This,together with the THN observations, confirms that the analysis by Amenomori etal. (2007) based on the Tibet III experiment in the northern hemisphere is notseriously biased. The best-fit amplitudes of the anisotropy, on the other hand,are only one third or less of those reported by the Tibet III experiment,indicating attenuation due to solar modulation. The rigidity dependence of theanisotropy amplitude in the sub-TeV region is consistent with the spectrumreported by Hall et al. (1999), smoothly extending to the Tibet III result inthe multi-TeV region. The amplitude at higher energies appears almost constantor gradually decreasing with increasing rigidity.
