Reconstruction and Modelling of Jet Pull with the ATLAS Detector

Weighted radial moments over the constituents of a jet have previously been shown to be an experimental handle on colour connections between the initiating partons. This note presents a study of the detector performance in reconstructing one such moment, the {\it jet pull} angle for jets produced in $t\bar{t}$ events with one leptonically decaying $W$ boson using 20.3 $\mathrm{fb}^{-1}$ of data recorded with the ATLAS detector at $\sqrt{s}=8$ \TeV.
