Using StRandomSelector to Artificially Reduce Track Efficiency
Updated on Mon, 2009-08-24 10:38. Originally created by wwitzke on 2009-08-24 08:17.In order to better estimate the error in the jet energy scales arising from Tpc efficiency error, we have been looking into the possibility of examining the effects of reducing jet efficiency artif

Linearity Check in fixed ecalgeo.g, take II
Abstract: The EEMC geometry (ecalgeo.g) has been modified to remove a bug which resulted in approximately 1 radiation length of lead being inserted at the shower-maximum depth. In this blog entry, the response of the modified geometry to various particles is determined over a range in energy from 0.5 to 200 GeV. For photons we find that the linearity of the simulated EEMC sampling fraction is good to better than 1% over the range of energies studied. Electrons above 2 GeV and neutral pions above 7 GeV exhibit similar linearities.
Linearity Check in fixed ecalgeo.g
Abstract: A bug in the EEMC geometry has been identified. Lines such as "Material Air isvol=0" have an unexpected (read undocumented) behavior: they create a new materi
