Sumario:An attempt to optimize the jet calibration implemented in ATLFAST package is described in the Note. A set of Z+1jet events have been simulated to get a new parameterization, and to complete the calibration. W bosons produced in ttbar events have been reconstructed. A simple fixed cone algorithm for the jet reconstruction has been tested for various values of the cone size and also for different processes such as WH (H-> bbbar) and W+jets. A new value of the cone size deltaR=0.6 has been found suitable for reconstruction of the jets sample selected with low pt-threshold.
