How to access the corrected chunks after d0correct
  ------------------------------------------------------------------


EM chunk:
--------------- 
see: analysis_example/src/D0ChunkAnalyze.cpp and analysis_example/rcp/D0ChunkAnalyze.rcp for an example.

  RCP emidAlgoRCP = rcp.getRCP("EMid_Algo");   // RCP for selecting the EMparticle chunk used
  vector<string> emidNestedRCP = rcp.getVString("EMid_SearchRCPs");
  EMparticleChunkSelector emAlgoSel(emidAlgoRCP,emidNestedRCP);
  edm::TKey<emid::EMparticleChunk> emKey = TKey<EMparticleChunk>(emAlgoSel);
  THandle<EMparticleChunk> emChunk = emKey.find(event);

with, in your RCP:
  RCP EMid_Algo = < emreco EMReco-scone-id >
  string EMid_SearchRCPs = ("clusterer","HMReco",)


Muon chunk:
-----------------

see: MuoCandidate documentation for details (http://www-d0.fnal.gov/phys_id/muon_id/d0_private/certif/p14/index.html)  

  RCP muonidAlgoRCP = rcp.getRCP("Muonid_Algo");
  MuonParticleChunkSelector muAlgoSel(muonidAlgoRCP);
  TKey<muonid::MuonParticleChunk> candKey = TKey<MuonParticleChunk>(muAlgoSel);
  THandle<MuonParticleChunk> candchunk= candKey.find(event);
 

with, in your RCP:
  RCP Muonid_Algo = <muonid MuoCandidateReco>

Jet chunk:
--------------

create a JetAlgoInfo for either JCCA or JCCB and use the method: 
JetAlgoInfo JetAlgoInfo::CorrectedJetAlgoInfo(JetAlgoInfo uncorrectedJetAlgoInfo);
to access the corresponding corrected jet chunk with good jets corrected for JES without muons and
JetAlgoInfo JetAlgoInfo::CorrectedMuJetAlgoInfo(JetAlgoInfo uncorrectedJetAlgoInfo);
to access the corresponding corrected jet chunk with good jets corrected for JES with muons

    string jetType = rcp.getString("JetAlgo_type");
    std::vector<float> jetValues = rcp.getVFloat("JetAlgo_values");
    std::vector<std::string> jetNames = rcp.getVString("JetAlgo_names");
    if ( jetNames.size() > 0 )
      while ( *jetNames.rbegin() == "" ) jetNames.pop_back();
    if ( jetValues.size() < jetNames.size() ) {
      cout << "D0ChunkAnalyze: inconsistent RCP values for the jet selection, disable it" << endl;
      jetNames.clear();
      jetValues.clear();
    }
    JetAlgoInfo uncorrected_jetAlgoInfo(jetType,jetValues,jetNames);
    JetAlgoInfo corrected_jetAlgoInfo=JetAlgoInfo::CorrectedJetAlgoInfo(uncorrected_jetAlgoInfo);
    JetChunkSelector jsel=JetChunkSelector(corrected_jetAlgoInfo);
    const TKey<JetChunk> jetKey(jsel);
    THandle<JetChunk> hjet = jetKey.find(event);


with for JCCA, in your RCP:
  string JetAlgo_type = "PreSCilcone"
  string JetAlgo_names = ( "towers" "coneSize" "Radius_of_Cone" "Min_Jet_ET")
  float JetAlgo_values = (    0.       0.3          0.7             8.      )
   

Missing ET chunk:
------------------------

you can access the corrected chunk as the uncorrected one:

    const TKey<MissingETChunk> metKey;
    THandle<MissingETChunk> metchunk = metKey.find(event);
