PreStripping18: Estimated bandwidth in Mb/s

Table of bandwidth (Mb/s) per stream and per WG:

Stream Charm RD BHQ Calib QEE B2OC SL B2CC Charmless Total
Dimuon 0.1 4.5 6.0   0.1     2.2   10.7
Charm 5.4   0.4             5.8
EW   0.2     5.5         5.6
Radiative   4.3           0.1   4.7
Semileptonic             4.3     4.3
CharmToBeSwum 4.2                 4.2
MiniBias       3.9           4.0
BhadronCompleteEvent           3.8       3.8
Bhadron   0.1 0.1     1.6   0.0 0.4 2.1
Calibration       0.4           0.4
CharmCompleteEvent 1.0         0.2 0.3     1.6
Leptonic     1.0   0.1         1.5
PID       0.3           0.3
Total 10.6 9.0 7.8 4.6 5.7 5.6 4.7 2.4 0.4 49.0

The following event sizes are assumed to calculate bandwidth:

Stream kB/evt
BhadronCompleteEvent 175
Calibration 135/4=34*
CharmCompleteEvent 137
Dimuon 152
EW 109
MiniBias 124
Radiative 148
Semileptonic 132
Charm 23
Leptonic 13
PID 18/4=4.5*
Bhadron 23
CharmToBeSwum 137*(0.25+0.10)=48*

* Only one copy of Calibration, PID and CharmToBeSwum streams will be kept instead of 4. In addition, 10% of CharmToBeSwum will be stored as full DST.

Trigger rate is taken to be 2680 Hz (condition for run 97120)
