Done With Muon Taking!
• Well, nearly:
– We may get a little bit more but not much .....
• What we have:
– Vertical:
– LAT 70x: 62h
– LAT 71x: 16h
– 1.9M events/h
– Horizontal:
– LAT 70x: 17h
» Part of it with the VDG!
– 1.1M events/h
• Processing:
– Most of it has been processed
– Catching up with the last few runs right now
– SVAC and Merit ntuples and digi.root files available
– Most of the recon.root files have been deleted

Reprocessing
• Reprocessing:
– Hope to start reprocessing at the end of next week!
– Will take at least a week to finish
– With ACD calibrations in the code!
– Finally! You will then get calibrated quantities in your
ntuples.
– Recon.root:
– We will keep the recon.root files for this processing
»
At least we will really, really try ..... :-)
– Muon hypothesis:
– Will reprocess a subsample using the muon hypothesis
» 10M Vertical + 10M Horizontal enough?
– Context information:
– Available in the SVAC ntuple
» Extended GEM counters etc
– Need to write the documentation .....
• Will make MC for all data taking configurations.
• Please look at the data now:
– This is the time to find problems ......

And Off You Go .....
• LAT:
– Already in the shipping container!
– Will continue testing until Tuesday
– Yes! It will be is connected up in the container.
Thursday: Off To NRL!
