void AddDetector (int id, TVector3 pos, double time, double sigma)
 Note about vectors The TVector3 class is used here instead of the utl::Vector and utl::Point classses. The reason of this election is that the independence of the coordinate system provided by both utl classes is obliterated in the inner workings of Minuit2 by the use of the individual vector coordinates. The data members of this class using vectors are the detector positions and the optional core position. They all have to be provided in the same coordinate system. The fitted axis is correspondingly expressed in the coordinate system used for positions. More...

Detailed Description

Reconstruction of the shower geometry.

Author
Diego Ravignani The axis direction and the impact time of the shower core on the ground are reconstructed from the time of the measured arrival times in a grid of detectors. This generic reconstruction, applied originally to the MD, can be also used for the SD or any detector array
