The code used by the almc applet to simulate displayed events is the same (apart from simpler medium settings used to speed up initialization and mmc being used for both mu/tau and neutrino propagation) as used for AMANDA, all calculations are done in 3d. However, to better represent the tracks, the projection on the plane containing the track and the Earth center is displayed in the main plot. The smaller insert contains a projection of the detector volume (with diameter 800 m and length 800 m) onto the xz plane. Since the projection of the muon points of entry to and exit from the detector volume does not always lie on the boundary of the cylinder projection, and the secondary showers are only recorded for the part of the muon (or tau) track which lies inside the detector, you may see muons which suddenly start and then stop producing showers at points well inside the insert box.

The last 100 km (or less if the track is shorter than that) of each track are plotted in a brighter shade of the track's color to help identify track endpoints. No scattering is implemented for neutrinos, however muons and taus will scatter if option "-scat" is used (disabled by default). The apparent non-zero angles between some tracks of the same event are artificial and are applied to show several overlapping tracks simultaneously (again, unless "-scat" option was used that results in visible scattering angles). Stopped muon and tau decay is disabled by default to help identify upgoing tracks; to enable use "-sdec".
