2. Data reprocessing Mar06:
mcr files for all_phys production (gb_nr=0) scratched
run smoothly since then
“A regime” rate: between 31 and 38 pb-1/day
End very close (weekend) (early next week)
Need to clean and resubmit dead jobs (2 days)
due to the stop

3. expected size for Bhabha at LSF=1:
Pending requests
Nguyen: 2006 data reprocessing (i.e. 240 pb-1)
with new  selection (~10 days)
algorithm not ready
ppg: 250 pb-1 Bhabha for 2002 luminosity (~1 week)
Beltrame: 250 pb-1 MC Bhabha at 1 GeV LSF=2 (~1 week)
Spadaro: 2004/05 MC Bhabha, EFF=~600nb
new Babayaga generator to be inserted
fix for 1-sided clusters problem still to be checked
generation cards should be:
ppg bha20bab
Beltrame eeg10
Spadaro eeg100
expected size for Bhabha at LSF=1:
~1.3 GB/pb-1  few TB needed

9. Comparison of different DBVs
Flavio:
~30 pb-1 used
minimum differences
efficiencies in agreement within 1s

Are they there
with higher DBV?
To be inquired
Need to compare different versions
21 vs 26 between and 35881
22 vs 26 between and 36400

27. Lack of tape space: what to do?
How much is needed to finish data reprocessing?
800 pb-1 missing x pb-1 ~1 TB = TB needed
Short term solution
scratch mcr all_phys (gb_nr=0) will free TB
115 for 2004/5 and 7 for 2001/2002
What else can be scratched?
35 TB of data with DBV  16
16 TB of 2005 data with DBV = 21
34 TB of 2005 data with DBV = 22
Different versions comparison more urgent!!!
