Description
Dear all,
I am dealing with vertex reconstructions and was exploring what information Delphes can provide me. I looked up the workbook and among the many attributes of a Track object are the following
'ErrorP, ErrorPT, ErrorPhi, ErrorCtgTheta, ErrorT, ErrorD0, ErrorDZ'.
The description says that they store the 'errors' in the respective quantities. However, I am not sure how the errors are obtained. Are these quantities smeared by a certain function in-built to Delphes? Can that function and its parameters changed according to ones needs? Also, does it follow some validated CMS or ATLAS tracker resolution data?
Thank you,
Debjyoti Bardhan

Hi,
in the standard CMS or ATLAS these variables are not filled. They are computed and filled by in specific cards that use vertexing such as this one:
