Hourly muon data collected from detectors housed in an underground (11 m.w.e.) vault at Mawson. Data are recorded from two viewing directions: (a) North - Zenith 24 deg., Azimuth 330 deg (P6, P7) and (b) South-West - Zenith 40 deg, Azimuth 205 deg (P9, P10). Data are available in raw form or count rates that have been corrected for atmospheric pressure variations. Detecting methods range from geiger counter telescopes, installed in 1972, to proportional counter telescopes, installed in 1982 and still in operation. This data contain normalised counting rate records from the combined north pointing proportional counter telescopes P6 and P7 and the southwest pointing proportional counter telescopes P9 and P10, corrected for atmospheric pressure variation. The telescope output consists of the sum of the 2-fold coincidence counting rates from two identical modules. The accidental rate is removed from the total coincidence rate using a resolving time difference method (See Jacklyn R M and Duldig M L, 20th Int. Cosmic Ray Conf. Papers, Moscow, Vol 4, pp. 380-383, 1987). Further information is also provided in ANARE Research Notes 102, 50 Years of cosmic ray research in Tasmania.
