compact_bunch Struct Reference

The compact_bunch struct is equivalent to the bunch struct except that we try to use less memory. More...

Detailed Description

And that has a number of limitations: 1) Bunch sizes must be less than 327. 2) photon impact points in a horizontal plane through the centre of each detector sphere must be less than 32.7 m from the detector centre in both x and y coordinates. Thus, sec(z) * R < 32.7 m is required, with 'z' being the zenith angle and 'R' the radius of the detecor sphere. When accounting for multiple scattering and Cherenkov emission angles, the actual limit is reached even earlier than that. 3) Only times within 3.27 microseconds from the time, when the primary particle propagated with the speed of light would cross the altitude of the sphere centre, can be treated. For large zenith angle observations this limits horizontal core distances to about 1000 m. For efficiency reasons, no checks are made on these limits.
