Description of fastjet::ConstituentSubtractor which can be used for event-wide or jet-by-jet correction:
No externally supplied rho, nor background estimator
The mass part (delta_m) will be also corrected.
Using different background estimator for rho_m as for rho
The rapidity of the particles will be kept unchanged (not pseudo-rapidity).
The information about nearby hard proxies will not be used.
Using parameters: max_distance = 0.3 alpha = 1
# 20 pileup events on top of the hard event
# read an event with 203 signal particles, 1714 background particles, 93 signal charged particles, and 813 background charged particles with pseudo-rapidity |eta|<4
