Overview

CLast contains I3CLastModule. It is a module that calculates the Tensor of Inertia (of light/charge rather than mass) about the Centre of Gravity to:

• Determine a first guess at the casacade direction and provides a fast and analytic seed for further cascade reconstructions.

• Determine the ratio of the smallest ToI eigenvalue to the total of all 3 eigenvalues; a value of 0.333… is maximal and implies the distribution of light is spherical, values less than this imply less and less spherical distributions of light.

See Calculations for information on the specific calculations performed. See Usage for scripts to use the I3CLastModule.
