<div>The latter should be possible, but not currently via the normal projection route: SmearedParticles inherits from ParticleFinder, while FastJets accepts a more specific FinalState projection as its source of particles. This is something to generalise, but last time I tried it turned out to be more involved than you might expect.</div><br><div>You should be able to use FastJets "interactively" via its calc() mechanism, though, e.g. somefastjetsproj.calc(smearedparticlesproj.particles()); somefastjetsproj.jets(). We could/should also make that neater...</div><br><div>In response to the earlier question (I'm just back online after holiday), there's nothing specific to particle charge about the SmearedParticles mechanism, but the generic built-in smearing functions are mostly for well-isolated, fairly hard, identified particles. Constituent-level smearing for jet (substructure) reco would require something more specific than the built-ins -- that's part of why we <em>don't</em> currently smear the constituents of smeared jets (although I forget, do we rescale their momenta to be consistent with the jet momentum?) You can write your own constituent-smearing function fairly easily, though, with as simple or complex a smearing algorithm as you need.</div><br><div>Andy</div><br><div><signature id="initial"><div><table cellpadding="0" cellspacing="0"><tbody><tr><td colspan="2"><div style="padding-bottom:15px;"><div><strong>Dr Andy Buckley, Lecturer / Royal Society University Research Fellow</strong></div><div>Particle Physics Experiment Group, University of Glasgow</div></div></td></tr><tr><td style="vertical-align:top;"></td><td><div style="font-size:0.9em;white-space:nowrap;border-left:2px solid gray;margin-left:20px;padding-left:20px;"><div><div></div><div></div></div></div></td></tr></tbody></table></div></signature></div><div class="gmail_quote_attribution">On Feb 28 2018, at 7:16 pm, Deepak Kar <deepak.kar@cern.ch> wrote:</div><blockquote><br><div><div><div>Hi all,</div><div><br></div><div>Following up on my previous email, is there a way I can use SmearedParticles as inputs to jet forming?</div><div><br></div><div>Thanks,</div><div>Deepak</div></div><div><br><div><div>On Mon, Feb 26, 2018 at 8:05 PM, Deepak Kar <<a href="mailto:deepak.kar@cern.ch" title="mailto:deepak.kar@cern.ch">deepak.kar@cern.ch</a>> wrote:</div><blockquote><div><div>Dear experts,</div><div><br></div><div>I am trying to calculate some jet substructure variables (using fastjet contrib) of a smeared jet.
