Detailed Description

real Jet information.

This class contains information for one single jet. That is, first, its momentum carrying information about its centre and pT, and second, its particle contents

sm_var2

double siscone_spherical::CSphjet::sm_var2

ordering variable used for ordering and overlap in the split–merge.

This variable is automatically set either to E_tilde or E depending on the siscone parameter.

Note that the default behaviour is E_tilde and that other choices may lead to infrared unsafe situations.

Note: we use the square of the varible rather than the variable itself

Note 2: for the overlap computation, we shall use the jet energy!
