class I3CLastCalculator

#include <I3CLastCalculator.h>

Core calculation class for I3CLastModule module.

This class contains a series of functions to calculate the tensor of inertia and related quantities. With this, you can calculate the inertia tensor of the hits, diagonalize the inertia tensor, and correct the direction of the longest eigenvector.

In addition, a simplified version of the cfirst algorithm is included so that the start time of the cascade can be estimated by looking at the times of hits that are close to the light cone assuming that the vertex is at the center of gravity. This implementation differs from the cfirst one in that it will return the time of the first hit in the event for an events that do not have a sufficient number of hits on/near the light cone. In this way, a seed will always have a start time &#8212; something that is required by subsequent likelihood fits.

And, finally, this code contains routines that parameterize the estimate of the cascade energy from the nchannels for IceCube AMANDA. These parameterization was obtained from cascade MC data.

class I3CLastModule : public I3ConditionalModule

#include <I3CLastModule.h>

Seed Estimator for Cascade.

The main module for generating a complete seed for cascade analysis uses the tensor of inertia reconstruction to estimate a direction, the COG to estimate a vertex position, and the cfirst-ish light-cone algorithm to estimate the start time (though, unlike cfirst, this code will always return a start time since, if the cfirst algorithm fails, it will return the hit time of the first hit in the event.)
