Description
Hi,
I'm working with track reconstruction and I need to smear tracks for the simulation. Each track is described by five perigee parameters and there exist tracker resolutions for each of the parameters. Looking at the cards, I can find just the resolution in PT for the charged tracks through the tracker. How can I implement the resolution in the four other track parameters in Delphes?

Hi,
I implemented this in my Hadron Smearing Module, but I'm encountering an error. It says that the DZResolutionFormula variable doesn't exist (as don't the others) (Error message "no such variable"). I can understand that this is to be expected since they aren't defined anywhere. Where should these variables be defined and how?
Hi
you can use the TrackSmearing module for that. It will apply an un-correlated smearing of the 5 track parameters.
See here for an example:
https://github.com/delphes/delphes/blob/master/cards/delphes_card_llptest.tcl#L66
Note that the values in that card are for test only and are not meant to reproduce existing performance.
