*TrackCalChunk
*TrackCalJetChunk

*ThumbNailChunk:

CPSClusterChunk (CPSTmbObj)
FPSClusterChunk (FPSTmbObj)
VertexCollChunk (VtxTmbObj)
*ChargedParticleChunk (ChTmbObj, ChIsoTmbObj)
*VtxChLinksChunk (newly created by UnpThumbNailPkg)
*EMparticleChunk (EmTmbObj)
-MuonParticleChunk (MuTmbObj)
*TauChunk (TauTmbObj)
*JetChunk (JetTmbObj, LeBobTmbObj)
*MissingETChunk (MetTmbObj)
CalStatusChunk (CalStatusTmbObj)
FPDDigiChunk (FPDTmbObj)
LMDigiChunk (LMTmbObj)

* These chunks should be dropped and regenerated from scratch.
- These chunk may need updating.

II.  Fixing synopsis.

1. Standard initialization (geometry, calibration, history, configuration).

2. SAMManager.

3. ReadEvent.

4. Update LumiInfoChunk.

5. Unpack ThumbNailChunk.  No need to unpack: em, tau, jet, met.
Do unpack charged particles, muons, vertices.

6. Drop ThumbNailChunk, TrackCalChunk, TrackCalJetChunk and other
chunks listed above.  Keep ChargedParticleChunk and VtxChLinksChunk 
temporarily.

7. Fix CalDataChunk warm cell problem (CalTowerTwo_HCKalone).  This is
the heart of fixing.

8. Make a reverse-engineered GTrackChunk from charged partgicels using
ChPartGTrackPkg.  For this we use the rcp option to simultaneously
make GTrackChLinksChunk to remember associations from the old charged
particles to GTracks.

9. Drop ChargedParticleChunk using process hook.

10. Calorimeter reconstruction (subset of <d0reco reco_cal>).  Omits
remaking Calt4_25Chunk.

11. Charged particle reconstruction using standard d0reco <d0reco
reco_chpart>).  Makes ChargedParticleChunk and TrackCalChunk.

12. Remake VtxChLinksChunk using VtxChLinksPkg to store associations
between remade charged particles and existing vertices.

13. Update MuonParticleChunk to reestablish links to new charged particles.

14. Redo other particle ids (em, tau, jet, met, links) using d0reco
standard rcps (not sure about links).  Jet reconstruction makes
TrackCalJetChunk and JetChunk.

15. Remake ThumbNailChunk.

16. Tag chunks and Write out thumbnail.

III.  Cvs Packages.

Here are some of the cvs packages that contain d0reco algorithms that should
be checked for consistency between p20.08.02 and p20.11.01.

1.  High level rcp files.
