PreStripping18: Estimated bandwidth in Mb/s (update)
Bandwidth per stream and per WG taking the DST size calculated with
DaVinci head of 28/02/2012, enabling DST packing and compression. Trigger rate is taken from Run 97120 (2680 Hz), and is multiplied by 2 for Charm streams and by 1.25 for other streams.

*) For calibration streams, only one copy will be stored, therefore in the bandwidth table their contribution is divided by 4.
**) For
CharmToBeSwum, this is the full DST size. In the bandwidth table, we assume 10% of this stream will be stored, plus microDST with the size/event as in Charm stream.
